The **Euclid Mathematics Contest**, offered by the **Centre for Education in Mathematics and Computing (CEMC)** at the **University of Waterloo**, is a written competition designed for senior high school students with a strong interest in mathematics. Aimed primarily at students in their final years of secondary school, the contest features challenging problems that emphasize logical reasoning, clear communication of solutions, and creative problem-solving rather than routine calculations. This contest is well-suited for students who enjoy enrichment beyond the standard curriculum, are preparing for university programs in **STEM fields**, or are considering competitive mathematics or related academic paths. Participants typically register through their schools, and school registration deadlines are set annually by the CEMC. Students should consult their math department or contest coordinator for current timelines and procedures. Taking part in the Euclid Contest can strengthen a student’s **college and scholarship applications**, particularly for mathematically intensive programs. Strong performance may be viewed as evidence of advanced mathematical ability, persistence with challenging material, and readiness for university-level coursework. Even for students who do not score at the top, preparing for and writing the contest can deepen conceptual understanding, build problem-solving resilience, and provide experience with a well-respected international mathematics competition.
