Organized by the University of Waterloo in Canada, the Euclid Mathematics Contest is hailed as the "TOEFL of the Math World". It serves as a crucial academic endorsement for high school students worldwide applying to top North American and British STEM programs. Its emphasis on process, logic, and full English solutions makes it a gold standard for assessing students' depth of mathematical thinking and ability to articulate ideas.
This article compiles the 2026 season's key timeline, exam focus, participation advice, and strategic value, helping you plan precisely and efficiently strive for a high score!
I. 2026 Euclid Mathematics Contest Key Timeline (Must Remember!)
| Item | Date | Notes |
|---|---|---|
| Exam Date | North/South America: March 31, 2026 (Tuesday) Other regions (including China): April 1, 2026 (Wednesday) |
Globally unified questions; Chinese candidates take it 1 day later |
| Registration Deadline | February 25, 2026 | ⚠️ Individual registration not accepted! Must be submitted through schools or authorized educational institutions |
| Registration Method | Organized by school / Registered through authorized training institution | Institution channels often close earlier (e.g., before Feb 20), be sure to confirm early |
| Exam Format | Offline paper-based written test, entirely in English, 150 minutes | Test papers are collected after the exam and cannot be taken away |
Suitable for: Students in grades 10–12 worldwide (high school years 1–3), especially those planning to apply to STEM majors such as mathematics, computer science, engineering, and physics.
II. Exam Content & Module Weights (Based on Recent Years' Analysis)
Euclid covers the core content of Canadian Grade 12 Mathematics, roughly equivalent to senior high school content + some pre-university knowledge in China. There is no out-of-syllabus content, but comprehensive application is heavily emphasized.
Core Modules and Weightings:
| Module | Weight | Key Topics |
|---|---|---|
| Probability & Combinatorics | ≈25% | Permutations and combinations (addition/multiplication principle); classical probability; grouping/coloring problems; introduction to expectation |
| Functions & Equations | ≈21% | Properties and graphs of linear, quadratic, exponential, and logarithmic functions; solving equations (including relationships between roots of cubic equations, remainder theorem); connections between function zeros and equations |
| Sequences & Series | ≈13% | Arithmetic/geometric sequences: general term and sum; recurrence relations; analysis of monotonicity and boundedness |
| Geometry & Analytic Geometry | ≈15% | Plane geometry proofs; properties of circles; coordinate method; vector applications |
| Trigonometry | ≈10% | Graph transformations; law of sines and cosines; trigonometric identities |
| Number Theory & Algebra | ≈10% | Divisibility, modular arithmetic, factorization, inequalities |
| Other (Sets, Logic, etc.) | ≈6% | Basic logical reasoning; set operations |
Trend insight: In recent years, the final challenging problems (Q9–10) often integrate functions + sequences + inequalities or geometry + algebra, emphasizing cross-module modeling skills.
III. Grade-Specific Participation Suggestions: Scientific Planning, Step-by-Step Progression
| Grade | Positioning | Goal | Preparation Advice |
|---|---|---|---|
| Grade 9 (Freshman) | Trial & Familiarization | Get acquainted with question types, adapt to English exam environment | Focus on the first 6 questions; master basic functions, equations, and elementary geometry |
| Grade 10 (Sophomore) | Systematic Award Pursuit | Achieve Certificate of Distinction (≥80 points) | Cover all modules comprehensively; strengthen probability/combinatorics and functions/equations |
| Grade 11 (Junior) | Peak Sprint | Strive for Honor Roll (≥90 points), create application highlights | Specialize in challenging problem types; enhance solution rigor and speed |
| Grade 12 (Senior) | Address Weaknesses | Supplement application materials, aim for scholarships | Even if not taken before, can still aim for Distinction as a supplement |
Golden window: Grades 10–11 are the best period to aim for awards—ample time, comprehensive knowledge, and application materials not yet finalized.
IV. Why Is Euclid Highly Recommended?
1. Hard Currency for Prestigious North American Admissions
University of Waterloo: Directly used for evaluating admissions to Math, CS, and Engineering programs; high scores can lead to entrance scholarships.
University of Toronto, UBC, McGill: Acts as a core proof of academic ability.
U.S. Ivy League & Top 30: Although not required, a score of 90+ can significantly enhance STEM application competitiveness.
UK G5: Admissions tutors for Oxford/Cambridge Engineering/CS programs highly regard its logical rigor.
2. Unique Value in Developing Core Skills
Compared to AMC (multiple-choice, emphasis on speed and tricks), Euclid focuses on full-solution questions, stressing logic and expression.
Mathematical modeling ability: Transforming text into symbols and equations.
Rigorous reasoning skills: Each step requires justification.
Academic writing in English: Describing mathematical ideas using standardized language.
