Canadian Mathematical Olympiad
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. The Olympiad plays several roles in Canadian mathematics competitions, most notably being Canada's main team selection process for the International Mathematical Olympiad.
Approximately 70 to 80 people qualify for and are invited to write the CMO each year. Students must not have written the Putnam Competition and must meet age, full-time school enrollment, and Canadian Citizenship (or permanent residency) requirements. Students do not have to be living in Canada, as long as they are Canadian citizens.
Participants are invited to write the CMO usually because of excellent results at the Canadian Open Mathematics Challenge (COMC). Approximately the top 50 students from the COMC earn invitations to the CMO. A Qualifying Repêchage (CMOQR) is offered as a "second chance" for the next highest 50 - 100 students from the COMC. About 20 students are chosen from the Repêchage and are then invited to the CMO.
Top students in certain other top Canadian competitions are also given invitations. The organizing committee may also invite participants based on their earlier CMO experience or their performance at APMO or USAMO competitions.
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.
There are several different types of rewards for doing well on the CMO:
- Six people are selected each year for Math Team Canada, trained and sent to the International Mathematical Olympiad, the pinnacle of high school mathematical competition.
- Gold, silver and bronze medals are awarded based the percentile you scored in.
- 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.
