Talk to a Euclid preparation advisor
The fastest way to reach the desk is enterprise WeChat: press the button below, or scan the QR code in the footer of any page. Tell the advisor your grade, school curriculum and target, and you will get a straight read on where you stand — registration, timing, and how to prepare for a paper that is marked step by step.
Grade 9–12, and whether you study the Chinese national curriculum, an international curriculum, or both — preparation paths differ.
The next paper is written April 6–7, 2027; registration through a test centre closes around March 11, 2027. Say which year you are aiming for.
A past-paper score, a school mark, or simply “never tried a full-solution contest” — any starting point is enough for a useful answer.
This desk operates authorized Euclid test centres in China and answers preparation and registration-service questions. Official contest business — school contest orders, result releases, certificate generation and appeals — runs through your school’s contest supervisor and the CEMC at the University of Waterloo. Appeals in particular are accepted only through the writing school or test centre, never from individual students. This site is an independent guide and is not affiliated with the CEMC or the University of Waterloo.
Eight questions, eight straight answers
Can a student register for the Euclid individually?
No. The Euclid Mathematics Contest is only written through schools registered with the CEMC or through authorized test centres — there is no individual registration channel. If your school does not run the contest, an authorized test centre seat is the standard route; the advisor can confirm availability in your city.
When does registration close for the 2027 Euclid?
The CEMC’s official ordering deadline is March 11, 2027, for the April 6–7 sitting, and schools begin placing orders from September 2026. China test-centre registration follows the same season and typically closes in early March — a month before the paper, earlier than many writers expect.
Who should write the Euclid, and in which grade?
The paper is set for students in their final year of secondary school, and most writers sit it in Grade 11 or 12. Strong younger students are welcome to write early — the CEMC encourages it — and many use a Grade 10 or 11 sitting as a rehearsal for a peak Grade 12 attempt.
Is the paper in English, and can I use a calculator?
The contest is written entirely in English, so comfortable mathematical reading matters. Calculators are permitted provided they have no CAS, internet, storage of notes, communication, or dynamic-geometry features — the standard scientific calculator used at school is fine.
What score earns a Euclid award?
The Certificate of Distinction goes to the top 25% of writers worldwide. In 2026 that line sat at roughly 66 / 100 against a world average of 52.2; in 2025 it was about 68. Each school’s top writer also receives a Contest Medal, and the highest-standing writers enter national and international honour rolls.
When do results come out, and how do I check them?
The CEMC releases results to schools roughly four to six weeks after the contest — typically mid-to-late May. Results go to the school or test centre that registered you, not to students directly, so writers in China check with their test centre; the score-inquiry page on this site explains the steps.
What does the Euclid cost?
Two different numbers, often confused: the CEMC’s official contest fee is $18 CAD per participant, ordered and paid by schools. Writing at an authorized China test centre is a separate all-in service (currently 599 RMB) covering the seat, proctoring and materials handling. Neither is refundable once ordered — the CEMC’s terms allow no cancellations.
How much does the Euclid help a university application?
The University of Waterloo weighs strong Euclid results in Faculty of Mathematics admissions and entrance-scholarship decisions, and recommends applicants write it. Beyond Waterloo, a Top-25% certificate is concrete, dated evidence of mathematical writing under exam conditions — useful for any STEM-leaning application, though no contest guarantees an offer.
