Canadian Mathematical Olympiad

Last updated

The Canadian Mathematical Olympiad [1] (CMO) is Canada's top mathematical problem-solving competition. It is run by the Canadian Mathematical Society. The Olympiad plays several roles in Canadian mathematics competitions, most notably being Canada's main team selection process for the International Mathematical Olympiad.

Qualification

Anyone wanting to qualify for the olympiads must take the COMC. [2] Approximately 100 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). [3] Approximately the top 50 students from the COMC earn invitations to the CMO. A Qualifying Repêchage [4] (CMOQR) is offered as a "second chance" for the next highest 75 students from the COMC. Approximately 30 students are chosen from the Repêchage and are then invited to the CMO. Top students in certain other top Canadian competitions may also be considered for invitations, a few top winners from Alberta High School Mathematics Competition (Part II) and from le Concours de l’Association Mathématique du Québec (AMQ – secondaire) get invited to write the CMO. The organizing committee may also invite participants based on their earlier CMO experience or their performance at APMO or IMO competitions.

Note that you don't have to get qualify for CMO if you are aiming for EGMO.

Competition Layout

The competition is three hours long. There are five questions on the CMO, each worth seven 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 ten questions long. In the 1970s, the exam length changed a number of times before finally stabilizing to five questions in 1979.

The CMS does not formally disclose its marking procedure, however in the past the following model was used:

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

Awards

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