Terms and Conditions of Entry

Prism Maths Challenge · Version 1.0 · In force from 16 August 2026 · Applicable to registrations made on or after that date

1. The organiser

1.1 The Prism Maths Challenge ("Prism", "the Challenge", "we", "us", "our") is organised by Mina Lee, trading as Prism Maths Challenge.

1.2 Correspondence: hello@prismmaths.org. School coordinators: schools@prismmaths.org.

1.3 Prism is a private competition. It is not a school, an examination board, a public authority, or an accrediting body.

2. Scope

2.1 These Terms and Conditions of Entry ("these Terms") govern entry to and participation in the Challenge and use of the website at prismmaths.org.

2.2 Registration or payment of a fee constitutes acceptance of these Terms by the registrant. Participation in a sitting constitutes acceptance by the entrant of clauses 8, 14 and 16, which bind the entrant as conditions of participation whether or not the entrant is the registrant. Clause 28.4 is unaffected.

2.3 These Terms incorporate:

  • (a) the Privacy Policy published on the website;
  • (b) the Competitions page at prismmaths.org, which states current round dates, paper formats, fees and divisions;
  • (c) any consent form completed at registration; and
  • (d) any written confirmation, invoice or joining instruction issued for a particular round.

2.4 Where these documents conflict, precedence runs: the consent form, these Terms, the Privacy Policy, the Competitions page, other materials. In respect of personal data, the Privacy Policy takes precedence over these Terms.

3. Definitions

  • "Entrant" — the student who sits a paper.
  • "Registrant" — the person or organisation who registers an entry and is party to this contract, as determined under clause 5.
  • "Responsible Adult" — where the entrant is under 18, the parent or legal guardian named at registration, or the school acting through its coordinator.
  • "Round" — one scheduled staging of the Challenge.
  • "Paper" — the question paper for a given grade level in a given round. Each paper is offered in two versions, of equal difficulty, sat in different exam windows.
  • "School Division" — the route in which a school administers the sitting on its own premises under its own invigilation.
  • "Home Division" — the route in which the entrant sits remotely under live invigilation. Available on the Grade 10 and Grade 12 papers only.
  • "Coordinator" — the member of school staff nominated as the school's point of contact.
  • "Invigilator" — the person supervising a sitting: on a School Division sitting, the member of school staff appointed by the school; on a Home Division sitting, the person appointed by us.
  • "Credentials" — the login details, participation code and joining instructions issued for a sitting.

4. Eligibility

4.1 The paper an entrant may sit is determined by grade, not by age. An entrant may sit the paper for their own grade or any paper above it. An entrant may not sit a paper below their own grade. Age determines which divisions are available, under clauses 4.4 and 10.1.

4.2 The grade declared at registration must be the grade in which the entrant is enrolled at the date of the sitting, under the curriculum their school follows. Where a curriculum uses year groups, the equivalences published on the Competitions page apply.

4.3 An entrant may sit more than one paper in a round, but not more than one paper at any one grade level. Each paper entered is sat in one division only, and a separate fee is payable for each under clause 6.2. The exam window for each is assigned under clause 5.8.

4.4 Entrants under 14 at the date of the sitting are eligible for the School Division only.

4.5 The registrant is responsible for the accuracy of all information submitted at registration, including the entrant's name, grade, school and contact address, and, on an individual entry, the entrant's date of birth. An entry containing a false or misleading declaration may be cancelled without refund and any resulting score voided.

4.6 Entries can be accepted only from territories served by our payment providers or from which payment by international bank transfer can be received, and in which acceptance is lawful. Entries cannot be accepted from territories subject to comprehensive international sanctions.

4.7 We may refuse or cancel any registration we reasonably believe to be fraudulent, duplicated, made in breach of these Terms, or made by or on behalf of a person excluded under clause 6.8, 8.7 or 19. Where the reason is not attributable to the registrant, the fee is refunded in full.

5. Registration and the contracting party

5.1 Entrants aged 18 or over may register on their own behalf and are the registrant for all purposes under these Terms.

5.2 Entrants under 18 may complete the registration form themselves and may give their own email address for correspondence under clause 5.4. The registration must additionally name a Responsible Adult and give that person's email address. The Responsible Adult is the registrant and is the party to this contract; the entrant is not.

5.3 An entry for an entrant under 18 is not accepted until the Responsible Adult has confirmed the entry and, where clause 10 applies, given the consent required under clause 10.6. Confirmation is obtained by such means as we specify at registration.

5.4 Correspondence. This clause applies to individual entries; on a school entry, clause 9.6 applies. Credentials, practice materials, results and certificates are sent to the address given for the entrant. Confirmation of entry, the invoice, cancellation and refund correspondence, and any matter arising under clause 10 or clause 19 are sent to the Responsible Adult. We may copy either party on any communication.

5.5 Individual entries are completed on the website: registration form, then payment. A confirmation page and a confirmation email follow. The contract is formed on issue of the confirmation email. Submission of the form, or the appearance of a charge, does not of itself form a contract. Where an entry cannot be accepted, any sum taken is refunded in full without delay.

5.6 School entries are completed by a coordinator: a registration form carrying the roster and the warranties at clause 9.3, then payment against invoice in accordance with clause 6.6. The contract is formed when we confirm in writing that payment has been received and the entry accepted. Until then the entry is provisional and no places are reserved.

5.7 Registration closes fourteen days before the paper. Late entries are accepted at our discretion, and where accepted may not include the practice materials ordinarily issued in advance.

5.8 Each paper is sat within one of two exam windows published for that paper on the Competitions page, on a single calendar day. An entrant may log in at any point within the window; the paper begins for that entrant at the moment of login and runs for 60 minutes, closing automatically. The window is longer than 60 minutes so that clause 11.2 can operate without extending a sitting beyond it. We assign each entrant's window according to division and location; windows are not selected by the registrant. Requests to move to the other window are accommodated where practicable if made before credentials are issued.

5.9 Sitting times are published in a stated time zone. Conversion to local time is the registrant's responsibility. A sitting missed through an error of conversion is treated as a non-attendance under clause 7.6, and clause 11.2 does not apply to it.

5.10 Credentials are issued at least seven days before the paper. They are issued to the address at clause 5.4 or, on a school entry, to the coordinator under clause 9.6. They are personal to the named entrant, must not be shared, and are void if used by any other person.

5.11 Before credentials are issued, an entrant's details, including the spelling of the entrant's name as it will appear on any certificate, may be corrected and, on a school entry, one named student substituted for another, at no charge. A change of window is subject to clause 5.8. After credentials are issued, changes are made at our discretion.

5.12 The registrant shall procure that the entrant observes clauses 8, 14 and 16. On a school entry, clause 9.3(c) also applies.

6. Fees, payment and tax

6.1 Fees are stated and charged in US dollars. The fee for each division is published on the Competitions page and displayed before payment. The fee displayed at the point of payment is the fee payable.

6.2 The fee covers, for one entrant in one round: the paper, access to the exam platform for the sitting, invigilation where invigilation is provided by us, marking, a score report, and any certificate to which the entrant becomes entitled under clause 13. On a school entry it also covers the practice materials issued for that round. On an individual entry, practice materials are optional and are charged separately at the sum published on the Competitions page. The fee does not cover a re-sit, a second paper, or entry to a subsequent round.

6.3 Method of payment. Payment is made against an invoice issued by us, by international bank transfer, on both individual and school entries. Card payment is not currently available. Where card payment is introduced, it will be taken on a page operated by an independent payment provider, and the registrant's card details will be given by the registrant directly to that provider. We do not receive, process or hold card details, and will not do so.

6.4 Tax. Fees are stated inclusive of any tax applicable to the supply, and no tax is added to the sum invoiced. Where consumption tax (VAT, GST, sales tax or equivalent) is chargeable in the registrant's territory in respect of the supply, and the registrant is a school or other business, the registrant is responsible for accounting for it to its own tax authority.

6.5 A bank or card issuer may apply its own foreign transaction or currency conversion charge. Such charges are a matter between the registrant and that institution.

6.6 School entries are paid in US dollars against invoice, by international bank transfer. Card payment is not available on a school entry. An invoice bearing a unique invoice number is issued by email on submission of the registration form; that number is to be quoted in the transfer reference field. Charges are to be instructed as "OUR", so that the full invoiced sum is received. Payment falls due on the date stated on the invoice. The entry is not accepted, and no credentials are issued, until payment is received in full; clause 5.6 applies. Where a transfer is received short by reason of correspondent bank deduction, the school remains liable for the shortfall and the entry remains provisional until the shortfall is paid.

6.7 Concessions. Funded or reduced-fee places may be offered from time to time. They are awarded at our discretion, are personal to the named entrant, are non-transferable and carry no cash value. An offer made in one round creates no entitlement in any other.

6.8 Payment disputes. Queries concerning a payment should be addressed to us in the first instance. A payment dispute or chargeback raised without prior contact, or raised after the paper has been sat, may result in cancellation of the entry, voiding of the score, and exclusion of the registrant from subsequent rounds. Clause 19.2 applies before a score is voided under this clause.

7. Cancellation and refund

7.1 A refund of the full fee is made only in the circumstances stated at clauses 4.7, 5.5, 7.3, 7.7, 10.12, 11.1 and 25.1, and where a refund is required by law. In every other case the provisions of this clause apply.

7.2 Application. Clauses 7.3 and 7.4 apply in the same way to an individual entry and to a school entry. No separate cooling-off period applies to an individual entry, save as provided by clause 7.5.

7.3 Cancellation more than 14 days before the paper. Where notice of cancellation reaches us more than 14 days before the date of the paper — that is, at any time up to the close of registration — the registrant receives a refund of the full fee paid, subject to the deduction at clause 7.10.

7.4 Cancellation 14 days or fewer before the paper. Subject to clause 7.5, where notice of cancellation reaches us 14 days or fewer before the date of the paper, no refund is due.

7.5 Statutory cancellation rights. Where the law of the registrant's territory confers on a consumer a mandatory right to cancel a distance contract, that right prevails over clauses 7.3 and 7.4 to the extent required by law. Notice must reach us before the paper begins. This clause does not apply once the entrant has begun the paper.

7.6 Non-attendance. Where an entrant does not sit at the allocated time without prior notice, no refund is due and no transfer is offered.

7.7 Cancellation or rescheduling by us. Where a round is cancelled, or moved to a date the registrant cannot accommodate, the registrant receives a refund of the full fee. The same applies where a change materially disadvantages the entrant, including a change of format, a substantially altered date, or a variation under clause 24.1.

7.8 Notice of cancellation takes effect on receipt by us at the address at clause 20.3, and the date of receipt determines which of clauses 7.3 and 7.4 applies.

7.9 Every refund arising under these Terms is of the full fee, subject to the deduction at clause 7.10.

7.10 Refunds are returned by the method used for payment. A refund of a payment made by bank transfer is returned by international bank transfer, to the account from which payment was made; any bank, correspondent or intermediary charges arising on the return of funds are deducted from the sum refunded, so the sum received is less than the sum paid. Where card payment has been introduced under clause 6.3 and a payment was made by card, the refund is returned to the instrument used. Refunds are not made in cash or to a third party.

7.11 No refund is due where an entry is cancelled or a score voided for breach of these Terms.

8. Conduct of the paper

8.1 Each paper comprises a fixed set of multiple-choice questions to be completed within a fixed window, as published for that round. Papers are set in English.

8.2 All entrants sit a paper of the same difficulty, under the same conditions and for the same duration, whichever division or exam window they are assigned. The published duration applies without variation. The assignment of exam windows is governed by clause 5.8.

8.3 Permitted at the desk: blank paper for rough working, and a pen or pencil. Nothing further, unless the paper states otherwise.

8.4 The following are prohibited for the duration of the sitting:

  • (a) assistance of any kind from another person, whether present or contacted remotely;
  • (b) any artificial intelligence tool, chatbot, solver or automated assistant;
  • (c) calculators of any description, including those built into a telephone, watch, tablet or computer;
  • (d) notes, textbooks, formula sheets or prepared working;
  • (e) any second device, screen, tab or window, save the device used to join the invigilation session on a Home Division sitting;
  • (f) any messaging, forum, streaming or file-sharing application;
  • (g) leaving the room without the invigilator's permission;
  • (h) photographing, screenshotting, filming, recording, copying or transcribing any part of the paper;
  • (i) recording, screenshotting or transmitting the invigilation session.

8.5 The content of a paper is confidential until published by us. Every entrant assigned to a given exam window sits within that same window, across time zones. Disclosure of any question to a person who has not yet sat that version of the paper, by any means, is a material breach of these Terms.

8.6 The entrant must be the person named on the registration. Sitting a paper in the place of another entrant, or permitting another person to sit in one's own place, voids both entries.

8.7 Entrants, registrants and coordinators shall conduct themselves civilly toward our staff and invigilators. We may terminate a sitting, cancel an entry and decline subsequent registrations in the event of abusive or threatening conduct.

9. School Division

9.1 The school nominates a member of staff as coordinator. All communication concerning a school entry is directed to that person. A change of coordinator is to be notified in writing.

9.2 The school is responsible for providing a suitable room, working devices and a stable connection, for supervising entrants throughout the sitting, for ensuring that clause 8.4 is observed, and for ensuring that no entrant has access to the paper before or after their allocated window.

9.3 By registering, the school warrants that:

  • (a) it is authorised to enter its students and to submit their personal data to us for this purpose, and holds whatever parental consent or lawful basis its own policies and applicable law require;
  • (b) the roster submitted is accurate, each named student is enrolled in the grade stated, and no student appears more than once;
  • (c) it will inform parents and students, before the sitting, that the entry has been made and of the requirements imposed on the entrant by these Terms; and
  • (d) it will hold credentials securely and issue them to each entrant only at the sitting.

9.4 School Division sittings are not filmed, streamed or recorded by us. No software is installed on school devices.

9.5 The school shall notify us promptly of any matter which may constitute a breach of clause 8, whether arising during the sitting or subsequently.

9.6 We do not correspond directly with students on a school entry. Credentials, score reports and any certificates earned are issued to the coordinator. Clause 5.4 does not apply to a school entry.

9.7 The school is liable for the fee in respect of every student on the accepted roster, whether or not each sits. Substitutions under clause 5.11 are made without charge. Withdrawal of a named student, and any reduction in headcount, is subject to clauses 7.3 and 7.4.

10. Home Division

10.1 The Home Division is available on the Grade 10 and Grade 12 papers only, to entrants aged 14 or over at the date of the sitting. An entrant sitting a paper above their own grade may enter the Home Division on that paper. Home Division entries are individual entries under clause 5.5; a school may not register an entrant for the Home Division.

10.2 The entrant requires a computer on which to sit the paper, and a second device with a working camera and microphone on which to join the Zoom session, positioned so that the entrant's upper body and desk remain in view for the duration. A tablet or telephone is suitable as the second device but is not sufficient for sitting the paper. The entrant also requires a stable internet connection, a room in which they can be alone for the duration, and a clear desk. Testing the configuration in advance is the registrant's responsibility.

10.3 Sittings are invigilated live over Zoom, in groups. Sittings are not invigilated one to one.

10.4 The camera on the device at clause 10.2 is to remain active for the duration of the sitting, showing the entrant's upper body and desk. The microphone is to be active for the checks at clause 10.5 and is muted during the paper itself; it must remain functional throughout and be unmuted immediately on the invigilator's instruction.

10.5 The invigilator may require the entrant to show the room, the desk and their rough paper at the commencement and at the conclusion of the sitting.

10.6 Sittings in the Home Division are recorded. Where the entrant is under 18, the recording is made in reliance on the consent of the Responsible Adult, which is obtained separately at registration under clause 5.3 and which the entrant cannot give on their own behalf. Where the entrant is 18 or over, the entrant's own consent is obtained.

10.7 Recordings are used solely to verify the integrity of the sitting. They are not published, used in marketing, disclosed to the entrant's school, or transferred to any third party, save where disclosure is required by law.

10.8 Recordings are deleted 30 days after publication of the results for that round. A recording forming part of an open investigation under clause 19 is retained until that investigation and any representations under clause 19.2 are concluded, and is then deleted.

10.9 The entrant should select a plain background and remove from view anything they do not wish an invigilator to see. The registrant is responsible for ensuring that other members of the household do not appear on camera at any point during the sitting, or within audio range during the checks at clause 10.5.

10.10 A Responsible Adult may be present in the room to assist with technical configuration before the sitting begins, and shall leave before the paper commences. No assistance may be given at any point during the sitting.

10.11 Invigilators do not contact entrants privately, by any channel, before or after a sitting. Any matter concerning the conduct of a sitting should be raised at hello@prismmaths.org.

10.12 Consent to recording may be withdrawn at any time before the sitting. On withdrawal the Home Division is not available. Where the entrant's school is running the Challenge and accepts the entrant onto its roster, the registrant may elect transfer of the entry to the School Division; otherwise the full fee is refunded. Clauses 7.3 and 7.4 do not apply to a refund under this clause.

10.13 Zoom is supplied by a third party on its own terms. Clause 11 applies.

11. Interruption of a sitting

11.1 Where an entrant cannot sit or cannot complete by reason of failure of the exam platform, of the invigilation session, of our scheduling or of our error — whether or not the failure is attributable to a third party supplying a service to us — we shall provide one of the following remedies, at our election: a further sitting, in the other exam window, within the same round; or a refund of the full fee. Where a further sitting within the round is available, it is offered first. Where a remedy under this clause is offered and declined, no further remedy is due. This states the whole of our obligation in respect of a failed sitting, subject to clause 21.

11.2 Where the failure is attributable to the entrant — their connection, device, power supply, late arrival, or interruption of the room — the invigilator shall permit a period of up to 10 minutes for reconnection while the sitting remains open, and shall not extend the paper beyond the published window. No refund is due.

11.3 Where the failure is attributable to the school on a School Division sitting, clause 11.2 applies as though references to the entrant were references to the school, and the reconnection period is administered by the school.

11.4 No compensation is payable in respect of travel, tuition, preparation or any other cost incurred in connection with a sitting that does not take place.

12. Marking, results and queries

12.1 Papers are marked against a fixed answer key.

12.2 Results are ordinarily published within 20 days of the paper. Publication may be delayed. Individual entrants receive a score report by email, together with any certificate to which they are entitled. Schools receive score reports and any certificates earned, issued to the coordinator.

12.3 Rankings are calculated within grade and within division. The School Division and the Home Division are ranked separately and are not comparable.

12.4 Where a grade and division combination has fewer than 10 entrants, we may decline to publish rankings for it, combine it with another such combination, or issue certificates without ranking, and shall state which course has been taken.

12.5 A query as to a mark — a clerical error, a mis-recorded answer, or a score inconsistent with the responses submitted — must be raised in writing within 14 days of publication of results. Errors established are corrected, including where correction affects an award already issued.

12.6 A reasoned challenge to a question may be raised within the same period. Where a question is found to be defective, the same remedy is applied to every entrant affected.

12.7 Results are final on expiry of the 14-day period, subject to clauses 13.4 and 19.3.

12.8 Marked scripts, question-level data concerning other entrants, and the personal data of any other entrant are not released.

12.9 A result in the Challenge is a result in a private competition. It is not a qualification, and no representation is made that it will be recognised by any school, university or authority.

13. Certificates, awards and prizes

13.1 Four tiers of recognition are awarded within each grade and division. Tiers (b) and (c), and the first limb of tier (d), are calculated by rank:

  • (a) Participation — awarded to every entrant who sits the paper. It is not calculated by rank.
  • (b) Distinction — awarded to entrants ranking in the top 20%.
  • (c) Merit — awarded to entrants ranking from the top 20% to the top 60%.
  • (d) Special Award — awarded to the entrant ranking first, and to any entrant whose submission under clause 14 is published in a subsequent round. The second limb is not calculated by rank and is not confined to one entrant in a grade and division.

13.2 Where a threshold at clause 13.1 produces a fractional number of entrants, the number is rounded to the nearest whole entrant. Where entrants are tied at a threshold, each tied entrant receives the higher tier. The tiers are determined whether or not rankings are published under clause 12.4. Where combinations are merged under clause 12.4, the tiers are determined across the merged combination.

13.3 Certificates are issued digitally, once, and bear the entrant's name exactly as given at registration. No certificate is reissued for any reason, including where lost, and no correction is made after issue. This clause does not apply to a correction required under clause 12.5 or clause 12.6, which is given effect by issue of a replacement certificate superseding the original. The registrant is responsible for checking the entrant's name at the point of registration and may correct it under clause 5.11.

13.4 A certificate or award may be withheld, withdrawn or reclaimed where a breach of clause 8 is established, whenever established.

13.5 One certificate is issued to an entrant in respect of each paper sat. Where an entrant qualifies for more than one tier on the same paper, the Special Award supersedes a Distinction, a Distinction supersedes a Merit, and a Merit supersedes a Participation certificate. A Special Award arising under the second limb of clause 13.1(d) is issued in respect of the round in which the problem is published.

14. Submission of problems

14.1 Any entrant may submit a problem for consideration in a future round. Entrants awarded a Special Award under the first limb of clause 13.1(d) are invited to submit, and their submissions are considered in a separate pool. Submission is optional and unpaid, and confers no advantage or disadvantage in the marking or ranking of any paper. Clause 13.1(d) is unaffected.

14.2 A submission by an entrant under 18 requires the knowledge and consent of the Responsible Adult.

14.3 Submission grants us a worldwide, royalty-free, perpetual and irrevocable licence to use, adapt, publish and reproduce the material in the Challenge and in our published materials. Copyright in the material remains with the author.

14.4 The author is credited by name where a problem is used, unless the author requests otherwise.

14.5 The author warrants that the material is their own original work and does not reproduce the work of another.

14.6 We are under no obligation to use any particular submission, and may edit any submission used. At least one submission from the pool at clause 14.1 is published in a subsequent round for each grade at which that pool contains a usable submission.

15. Publication of results

15.1 An entrant's name is not published by us in connection with a result or ranking unless the registrant has given consent under clause 15.2. Absent that consent, a ranking or list of results we publish for a round identifies an entrant, if at all, by candidate number, grade, division and score only.

15.2 A registrant may consent, at registration or at any time before publication, that the entrant's name be included in a published ranking or list of results, on the website and in materials issued to participating schools. Consent given under this clause may be withdrawn at any time before publication. Consent, or its absence, does not affect eligibility for any award.

15.3 We may publish anonymised aggregate statistics, including score distributions, question-level performance and participation by region or curriculum, from which no individual entrant is identifiable. Consent under clause 15.2 does not extend to aggregate statistics.

15.4 An entrant's name, image or likeness is not used in advertising without separate written consent. Where the entrant is under 18, that consent is given by the Responsible Adult. Where the entrant is 18 or over, it is given by the entrant.

16. Intellectual property

16.1 Papers, solutions, marking schemes, score reports, certificates, the Prism name and mark, and the contents of the website are our property or that of our licensors. Clause 14.3 is unaffected.

16.2 An entrant may retain a copy of a paper as published by us for their own study. Nothing in this clause permits an act prohibited by clause 8.4(h). A participating school may use a past paper internally with its own students for teaching purposes.

16.3 Without our written permission, no person may reproduce a paper commercially; use our papers or solutions in paid tuition, coaching, publishing or a competing competition; sell, licence or distribute our materials; or upload them to a question bank, file-sharing service or subscription service.

16.4 Clause 16.2 does not permit disclosure of a live paper. Clause 8.5 governs until publication.

16.5 Our name and mark may not be used so as to suggest an endorsement, partnership or accreditation that does not subsist.

17. The website

17.1 No person may attempt to gain unauthorised access to the website or the exam platform, interfere with their operation, introduce malicious code, scrape at scale, or use either unlawfully. Access may be suspended where we reasonably believe this clause has been breached.

17.2 The website may link to sites we do not control, and we accept no responsibility for their content. No warranty is given that the website will be available uninterrupted or free of error.

18. Personal data

18.1 The collection, use, disclosure, storage and deletion of personal data, including recordings and the personal data of children, is governed by the Privacy Policy published on the website, which forms part of these Terms.

18.2 Personal data may be processed in or transferred to territories other than that in which the registrant resides, our processors operating internationally.

18.3 Marketing correspondence is sent only to persons who have opted in and carries an unsubscribe facility. No marketing correspondence is sent to an entrant under 18.

18.4 On a school entry, the school determines what data concerning its students is submitted to us and is responsible for the lawful basis on which it does so. We process that data to deliver the Challenge.

18.5 No permanent record of results, certificates or entrant data is retained. All information relating to a round, including entrant names, scores, rankings and certificates, is deleted following that round, within the period stated in the Privacy Policy. This clause does not apply to:

  • (a) information forming part of an open investigation under clause 19, which is retained until that investigation is concluded and is then deleted, save as provided at limb (d);
  • (b) results published under clause 15, which may remain publicly available;
  • (c) problems submitted under clause 14 and the contact details of their authors, retained for so long as the problem may be used;
  • (d) a record of a person excluded under clause 6.8, 8.7 or 19, and of any award withheld, withdrawn or reclaimed under clause 13.4, limited to the details necessary to give effect to the exclusion or the withdrawal, retained for so long as it has effect;
  • (e) the email address of a person who has opted in to marketing correspondence under clause 18.3, retained until that person unsubscribes, and thereafter a record of the unsubscription sufficient to ensure that no further marketing correspondence is sent to that address; and
  • (f) data obtained in the course of approaching a school to offer the Challenge, retained for so long as the school is a prospective or actual participant, and thereafter a record sufficient to ensure that no further approach is made to a person who has asked not to be approached.

19. Malpractice, disqualification and exclusion

19.1 Where we have reasonable grounds to believe clause 8 has been breached, we may investigate. Evidence may include invigilator reports, the recording of a Home Division sitting, exam platform activity logs, and information supplied by a school.

19.2 Before a final determination voiding a score, we shall notify the registrant and, on a school entry, the coordinator, of the substance of the matter, and shall allow a period of not less than 7 days for representations.

19.3 Where a breach is established we may, in proportion to the breach: void the score; withhold or reclaim a certificate or award; exclude the entrant from subsequent rounds; exclude a school from subsequent rounds; and notify the school of a finding concerning its own student.

19.4 No refund is due where a score is voided or an entry cancelled under this clause.

19.5 Our determination under this clause is final as between the parties, subject to clause 26. Clauses 27 and 28.7 are unaffected.

20. Notices

20.1 Communication is by email. The registrant is responsible for providing a working address, maintaining it, and monitoring spam and quarantine filters in the period surrounding a round.

20.2 We accept no responsibility for a missed sitting arising from our correspondence being filtered, blocked by a school mail server, or directed to an address supplied incorrectly. Credentials returned undelivered are re-sent once to the same address.

20.3 Notices to us under these Terms are to be sent to hello@prismmaths.org and take effect on receipt.

21. Liability

21.1 Nothing in these Terms limits or excludes liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other matter which cannot lawfully be limited or excluded.

21.2 Subject to clause 21.1, our total liability arising out of or in connection with an entry, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the fee paid in respect of that entry.

21.3 Subject to clause 21.1, we are not liable for loss of opportunity, loss of an anticipated place, award or ranking, loss of reputation, distress, or any indirect or consequential loss.

21.4 The Challenge is provided with reasonable care and skill. No warranty is given that the website or the exam platform will be uninterrupted or free of error. We are not liable for the acts, omissions or outages of third-party services beyond our reasonable control. Where such a failure prevents an entrant from sitting or completing, clause 11.1 applies and states the whole of our obligation.

21.5 Physical supervision of entrants is not undertaken by us. On a School Division sitting, supervision and duty of care rest with the school. On a Home Division sitting, they rest with the Responsible Adult, or with the entrant where the entrant is 18 or over. The function of an invigilator appointed by us is confined to observing the sitting.

22. Indemnity by schools

22.1 This clause applies to schools only and does not apply to individual registrants.

22.2 A school shall indemnify us against any claim, loss or cost incurred as a result of that school's breach of clause 9.3, including any claim brought by a parent or student in respect of data submitted to us by the school without authority.

23. Events outside our control

23.1 We are not liable for failure or delay in performance where the cause lies outside our reasonable control, including internet or telecommunications failure, failure of a third-party platform, power failure, natural disaster, epidemic, civil disruption, war, industrial action, or the act or restriction of a government or public authority.

23.2 Where such an event prevents a round from proceeding, clause 7.7 applies.

24. Variation

24.1 Of the competition. Round dates, sitting times, paper format, question count, duration, division structure, fees, thresholds and awards may be varied for future rounds. Variations are published on the Competitions page. A variation made after registration but before the sitting is notified by email, and clause 7.7 applies where it materially disadvantages the entrant.

24.2 Of these Terms. These Terms may be amended. Each version is dated, and the version in force at the moment of registration governs that entry. An amendment does not apply retrospectively to a registration already accepted unless it is more favourable to the registrant or is required by law.

25. Suspension and discontinuation

25.1 The Challenge may be suspended or discontinued in whole or in respect of a grade level or division. Where this occurs after acceptance of registrations for a round not yet sat, those registrations are refunded in full.

25.2 Discontinuation does not affect a result already published or a certificate already issued.

26. Complaints

26.1 Complaints are to be sent to hello@prismmaths.org. They are considered as soon as reasonably practicable.

26.2 Clause 26.1 should be exhausted before any further step is taken.

27. Governing law and jurisdiction

27.1 These Terms, and any dispute arising out of them, are governed by the laws of the Republic of Korea.

27.2 Consumers. Where the registrant is an individual acting outside the course of a business, clause 27.1 does not deprive them of the protection of any mandatory provision of the law of the territory in which they habitually reside. Such a registrant may bring proceedings in the courts of that territory, and we shall bring any proceedings against them in those courts.

27.3 Schools and other organisations. The courts of Seoul, Republic of Korea have exclusive jurisdiction.

28. General

28.1 Severance. Where any provision is held invalid or unenforceable, the remainder continues in force and the provision is treated as modified to the minimum extent necessary to render it enforceable.

28.2 Waiver. Failure or delay in enforcing a right under these Terms does not constitute a waiver of it.

28.3 Assignment. The registrant may not transfer their rights or obligations without our written consent. We may transfer ours to a person or entity assuming the running of the Challenge, provided the registrant's rights are not reduced, and shall give notice of doing so.

28.4 Third parties. Only the registrant and we may enforce these Terms. An entrant who is not the registrant has no independent right of enforcement, without prejudice to any right arising under law.

28.5 Entire agreement. These Terms, together with the documents at clause 2.3, constitute the whole agreement in respect of an entry and supersede any prior representation, save in respect of fraudulent misrepresentation.

28.6 Language. These Terms are written in English. Any translation is provided for convenience and the English text governs.

28.7 Statutory rights. Nothing in these Terms affects any right arising under the mandatory consumer law of the registrant's territory which cannot lawfully be varied by agreement.
