On the international mathematics competition stage, the Euclid Mathematics Contest, organized by the University of Waterloo in Canada, has become a highly sought-after goal for many Chinese high school students, thanks to its strong recognition in admissions to prestigious North American universities. However, many students preparing for the competition experience a profound sense of “disconnect” when facing real problems: despite the heavy computation and depth of Chinese high school mathematics, why do they still find themselves “stuck” when approaching Euclid problems?
What are the actual differences between the Chinese high school mathematics curriculum and the Euclid Contest? And how can we prepare differently based on our Chinese educational background? Today, we will break down this topic in detail.
I. Clash of Core Philosophies: Exam Skills vs. Mathematical Inquiry
The Chinese high school mathematics teaching system is heavily influenced by the college entrance examination (Gaokao). Its preparation logic is highly focused on “problem-solving techniques” and “quick solutions.”
The Philosophy of Chinese Mathematics: “Speed, Accuracy, and Decisiveness.” It emphasizes using specific formulas and techniques skillfully within a limited time to arrive at the correct answer. This cultivates strong computational ability and problem-solving resilience.
The Philosophy of the Euclid Contest: “Rigor and Exposition.” It requires not only the correct result but also a clear and complete demonstration of your thought process. The Euclid’s problem style is closer to an introductory university mathematics test, focusing on the logic of mathematical reasoning and rigorous proof procedures.
The Fundamental Difference: Chinese math exams usually only require you to submit the final answer, whereas the Euclid requires you to submit your “thinking process.” Many students who are used to solving problems quickly but cannot write rigorous arguments often lose significant step marks in the Euclid.
II. Compatibility of Knowledge Systems: “Strengths” and “Weaknesses” of the Chinese Foundation
1. Our Strengths: Algebra and Functions
Chinese high school mathematics provides intensive training in algebraic manipulation, trigonometric function handling, and function graph analysis. In the Euclid Contest, problems in these areas are often “easy points” or even “easy wins” for Chinese students.
2. Our Weaknesses: Combinatorics and Probability
In the Euclid Contest, combinatorial counting, probability theory, and some number theory problems have a significantly different emphasis from the Chinese high school curriculum. Chinese math classes often train permutations and combinations through extensive problem drills, but the Euclid places more emphasis on the rigor of case-based classification and the comprehensiveness of logical derivation.

III. Differentiated Preparation Plan: From “Problem-Solving Machine” to “Mathematical Thinker”
If you want to smoothly transition from the Chinese math system to the Euclid Contest, you need to adjust your preparation approach strategically:
Phase 1: Restructuring Your Mindset – From Answer to Logic
Habit Change: In your daily practice, even if you can see the answer immediately, force yourself to write out the complete process. The Euclid’s grading logic is “step-by-step scoring.” As long as your logical chain is complete, the process marks are often more important than the final answer itself.
Action: Practice writing “mathematical expositions in English.” Chinese students sometimes use non-standard notation when translating physics terms or mathematical symbols. Try to practice writing proofs in English to ensure your mathematical expressions are concise and accurate.
Phase 2: Targeted Attack on Weaknesses – Combinatorics and Geometry
Geometric Perspective: Geometry problems in the Euclid Contest are often not limited to “analytic geometry”; they favor “pure geometric proofs.” You need to revisit the geometric properties from middle school, learning to use circle properties, triangle congruence and similarity, and angle relationships for derivation, rather than relying solely on coordinate systems.
Combinatorial Perspective: Systematically tackle combinatorial counting problems. Learn to use “enumeration,” “induction,” and “symmetry analysis.” Do not try to find a universal formula; instead, learn to extract counting principles from specific contexts.
Phase 3: Full-Length Mock Tests and Process Review
Practice Strategy: Select real Euclid problems from the past 5-8 years and simulate the test conditions according to the official time limit (2.5 hours).
Key Review Step: After completing the problems, you must study the official “Full Solution” provided by the University of Waterloo. Observe how their standard answers achieve “conciseness and logical rigor.” Compare your own writing to see if there are logical leaps or redundant expressions.
IV. Advice for Parents – Avoiding Common Pitfalls
Reject the “Drill-and-Kill” Approach:
The Euclid does not require you to solve thousands of problems; it requires deep insight into the essence of mathematics. Instead of blindly practicing, focus on understanding the logic behind case-based classification in each mistake.
Do Not Underestimate the Importance of Steps:
Many students are used to writing “scratch-pad thinking” during practice, which leads to non-standard answers in the actual exam. From now on, require that every practice problem be written according to the standards of a “formal exam essay question,” cultivating a habit of rigorous mathematical expression.
Frequently Asked Questions
Is a domestic maths background compatible with this contest?
Partly, and knowing which part matters. Algebraic manipulation, trigonometric handling and function analysis are trained intensively in a domestic classroom, and those transfer directly. What does not transfer is the expectation of writing a complete argument for a reader, because school assessment mostly rewards reaching the right value quickly. The compatibility question is therefore less about topics than about what counts as a finished answer.
Where are the strengths and the weak points?
Strength: computation and function work, often above the level the paper assumes. Weak point: open-ended geometry where no standard configuration is handed to you, and any question where the marks follow the explanation rather than the result. Students are often surprised that their strongest school topics are the ones where they lose the fewest marks, and their weakest are not topics at all but habits.
What should change in daily practice?
One habit: stop when you reach the answer, then write the argument as if someone else has to mark it. Doing that on problems you already solved costs little time and directly trains the thing the paper measures. Volume of practice matters far less here than it does for a domestic examination.
