COMC Questions and Answers

What is the COMC exam?

The Canadian Open Mathematics Competition (COMC) is a national math contest organized by the Canadian Mathematical Society. It serves as a gateway to the Canadian Mathematical Olympiad (CMO) and other international competitions. The contest is open to high school students in Canada and participating international locations, testing problem-solving skills across algebra, geometry, number theory, and combinatorics.

How many questions are on the COMC?

The COMC contains 12 questions divided into three sections of increasing difficulty. Section A has 4 questions worth 4 points each, Section B has 4 questions worth 6 points each, and Section C has 4 questions worth 10 points each. The total possible score is 80 points, and all answers require full written solutions rather than multiple choice.

Who is eligible to write the COMC?

Any student enrolled in a Canadian high school or CEGEP is eligible to write the COMC. International students, including those in the United States, may also participate if their school registers through the Canadian Mathematical Society. There is no minimum age requirement, so younger students with strong math skills frequently compete alongside senior high school students.

How do I register for the COMC?

Registration for the COMC is handled through your school. A teacher or school administrator must register as a contest coordinator through the Canadian Mathematical Society website and then enroll individual students. The registration fee is typically around $3 to $5 CAD per student. Schools outside Canada can also register by contacting the CMS directly for international participation details.

What is the format of the COMC?

The COMC is a written examination lasting 2 hours and 30 minutes. Students must provide full solutions with complete mathematical justification for each problem. Partial marks are awarded based on the quality of reasoning shown. Unlike multiple-choice contests, the COMC emphasizes proof-writing and clear mathematical communication, making solution presentation as important as arriving at the correct answer.

How does the COMC differ from other math competitions?

The COMC stands apart from contests like the AMC or Waterloo competitions because it uses exclusively written-solution format rather than multiple choice or short answer. It also serves as the official qualifier for the Canadian Mathematical Olympiad. The difficulty ramps significantly from Section A to Section C, with the final problems approaching olympiad-level challenge and requiring creative proof techniques.

What are the best ways to prepare for the COMC?

The most effective preparation strategy is working through past COMC papers, which are available on the Canadian Mathematical Society website with official solutions. Focus on building proof-writing skills and practicing problems from each section separately. Supplement with resources like Art and Craft of Problem Solving or problems from similar contests such as the AMC 10/12 and AIME for building the problem-solving techniques needed for Sections B and C.

What happens after I write the COMC?

After the COMC, papers are graded by the Canadian Mathematical Society and results are typically released within a few weeks. Top-scoring students are invited to write the Canadian Mathematical Olympiad (CMO), which is the next level of competition. Strong COMC performance can also lead to invitations for math enrichment programs and serves as a recognized achievement on university applications, particularly for STEM programs.
