The Canadian Mathematical Olympiad (CMO), is, as the name suggests, the national mathematical Olympiad of Canada. It is run by the Canadian Mathematical Society and sponsored by the company Sun Life Financial.^[1] The Olympiad plays several roles in Canadian mathematics competitions, most notably being Canada's main team selection process for the International Mathematical Olympiad. ^[2]

[edit] Qualification

Approximately 70 to 80 people qualify for and write the CMO each year.

Qualification for the CMO is usually through the Canadian Open Mathematics Challenge, though only "official" participants of that contest can enter. Generally, the cutoff for the CMO on that contest is in the 70s.^[3]

[edit] Contest Layout

The contest is three hours long. There are 5 questions on the CMO, each worth 7 marks, for a total of 35 points. Each problem is graded the same way as it is on the IMO.

From 1969 to 1972, the CMO was 10 questions long. In 1973, this was shortened to 7 questions. It alternated between 7 and 8 before finally stabilizing to five questions in 1979.

Two graders will grade the questions. If there is a dispute between the graders by more than one point, they will reconsider the problem until a consensus was reached.

The grading is considered as follows:

• If no work was done or very insignificant progress was made, the answer is graded zero.
• If significant progress is made, marks of 1, 2, or 3 will be given, depending on the amount progress toward solving the problem.
• Marks of 4 or 5 are given for answers that are essentially correct, but are poorly presented or lack showing of work in some areas.
• If the solution has a minor error that can be trivially fixed, it is given a 6.
• An absolutely perfect solution is awarded a mark of 7. This might be given if there is an error in the writing that does not affect the solution in any meaningful way.

[edit] Awards

There are several different types of rewards for doing well on the CMO:

• Six people are selected each year for the Canadian International Mathematical Olympiad team, the pinnacle of high school mathematical competition. ^[4]
• Gold, silver and bronze medals are awarded based the percentile you scored in.^[5]
• The person who scores first place receives $2000 in cash. Second place receives $1500, and third place receives $1000. Another six students receive honourable mentions, and $500. Students receiving cash prizes must not have written the Putnam Competition.
