The Canadian Intermediate Mathematics Contest (CIMC math contest) is one of the most rewarding competitions a Grade 9 or 10 student can enter. It’s challenging enough to set top students apart \u2014 but with the right preparation, it’s genuinely achievable.<\/p>\n\n\n\n

This guide covers everything you need: what the CIMC is, how it’s scored, what topics appear, and how to build a preparation plan that actually works.<\/p>\n\n\n

What Is the CIMC Math Contest?<\/h2>\n\n\n\n

The CIMC (Canadian Intermediate Mathematics Contest) is a national mathematics competition run by the Centre for Education in Mathematics and Computing (CEMC) at the University of Waterloo. It is open to students in Grades 9 and 10 across Canada and attracts tens of thousands of entries each year.<\/p>\n\n\n\n

The contest is held each November and is administered through participating schools. It’s one of the key CEMC contests \u2014 alongside the AMC 8<\/a>, AMC 10<\/a>, Gauss<\/a>, Cayley<\/a>, and Fermat<\/a> \u2014 and is widely seen as a meaningful credential for students aiming at competitive university programmes.<\/p>\n\n\n\n

Strong performance on the CIMC math contest can also serve as preparation for higher-level CEMC contests such as the Canadian Open Mathematics Competition (COMC) and, eventually, the Canadian Mathematical Olympiad (CMO). For a full overview of where the CIMC sits within the Canadian competition landscape, see our guide to math competitions in Canada<\/a>.<\/p>\n\n\n\n

CIMC Math Contest Eligibility and Format<\/h2>\n\n\n\n

Who can enter?<\/strong>
The CIMC math contest is designed for Grade 9 and Grade 10 students. There is no strict restriction on Grade 11 or 12 students entering, but the contest is intended as an intermediate-level challenge, and most participants are in the target grades.<\/p>\n\n\n\n

When is it held?<\/strong>
The CIMC math contest takes place annually in November. Schools register through the CEMC website, and students write the contest at school during a designated session.<\/p>\n\n\n\n

Format at a glance:<\/strong><\/p>\n\n\n\n

Feature<\/th>Detail<\/th><\/tr><\/thead>
Duration<\/td>75 minutes<\/td><\/tr>
Part A<\/td>10 multiple-choice questions<\/td><\/tr>
Part B<\/td>4 full-solution questions<\/td><\/tr>
Calculators<\/td>Not permitted<\/td><\/tr>
Negative marking<\/td>None<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Part A tests speed and accuracy across a broad range of topics. Part B demands written solutions with full working shown \u2014 marks are awarded for method and reasoning, not just the final answer.<\/p>\n\n\n\n

What Topics Does the CIMC Math Contest Cover?<\/h2>\n\n\n\n

The CIMC draws on the Canadian intermediate curriculum but extends well beyond what most students encounter in the classroom. Students who prepare only from school material often find the contest significantly harder than expected.<\/p>\n\n\n\n

Core topic areas include:<\/p>\n\n\n\n

Number Theory<\/strong>
Divisibility, prime factorisation, greatest common divisors, least common multiples, and modular arithmetic. Questions often involve creative approaches to seemingly simple number problems.<\/p>\n\n\n\n

Algebra<\/strong>
Systems of equations, quadratics, inequalities, and algebraic manipulation. Expect problems that require multi-step reasoning rather than formula application.<\/p>\n\n\n\n

Geometry<\/strong>
Properties of triangles, circles, quadrilaterals, and coordinate geometry. Area and perimeter problems frequently involve non-obvious constructions. Our guides to special triangles in trigonometry<\/a> and tangent lines to a circle<\/a> cover two of the most tested geometric concepts.<\/p>\n\n\n\n

Combinatorics and Counting<\/strong>
Permutations, combinations, the pigeonhole principle, and basic probability. These are often the most unfamiliar topics for students who haven’t studied contest mathematics before.<\/p>\n\n\n\n

Sequences and Series<\/strong>
Arithmetic and geometric progressions, pattern recognition, and sum formulas.<\/p>\n\n\n\n

The CEMC publishes past papers on their website, which give the clearest picture of the style and difficulty of questions.<\/p>\n\n\n\n

\n\n\n\n

How Is the CIMC Math Contest Scored?<\/h2>\n\n\n\n

Part A:<\/strong> Each of the 10 multiple-choice questions is worth 4 marks. Full marks for a correct answer; no penalty for incorrect answers. Maximum: 40 marks.<\/p>\n\n\n\n

Part B:<\/strong> The 4 full-solution questions are worth 10 marks each. Partial credit is awarded, so students should always show their working \u2014 even an incomplete solution can earn several marks. Maximum: 40 marks.<\/p>\n\n\n\n

Total: 80 marks<\/strong><\/p>\n\n\n\n

Scores are reported individually and by school. CEMC publishes national and provincial results, and high-scoring students receive certificates of distinction. Top performers may be invited to consider further CEMC competitions.<\/p>\n\n\n\n
