The 2021 Canadian Open Mathematics Challenge — Oct 28/29


The Canadian Open Mathematics Challenge (COMC) is Canada's premier national mathematics competition open to any student with an interest in and grasp of high school math. The purpose of the COMC is to encourage students to explore, discover, and learn more about mathematics and problem solving. The competition serves to provide teachers with a unique student enrichment activity during the fall term.

Approximately 80 top-ranking students from the COMC and the Canadian Mathematical Olympiad Qualifying Repêchage (CMOQR) will be invited to write the Canadian Mathematical Olympiad (CMO). Based on the results from the COMC, the CMO and other national and international mathematics competitions and camps, the Canadian Mathematical Society IMO Committee will then select six students as part of Math Team Canada to travel to, and compete in, the International Mathematical Olympiad (IMO).

Top COMC female contestants will also qualify to be part of Girls’ Math Team Canada to represent Canada at the European Girls' Mathematical Olympiad (EGMO). EGMO is an international mathematics competition.

Depending on their grade level and performance, students participating in the COMC will also have the opportunity to be considered for university scholarships, get invited to math camps, garner awards, and win prizes.

Thank you for participating in the 2021 COMC!

The unofficial solutions (PDF) are now available for download. In January, we will publish the "official solutions".

COMC 2021 Competition:

Preliminary exam scores have been released to teachers! Teachers can view them by logging into their school accounts.

Caveat :
• Validation of high scoring exams by a team of experts is still underway to ensure that all high scoring COMC exams have been uniformly and correctly graded. This involves Canadian exams scoring 55 or above in the initial grading, with slightly higher cut-offs for international exams. These exams could see slight score changes in the coming week as the validation process is completed.

Official scores, award winner information and the random prize draw results will be released in mid-January. At that time, teachers will have access to the official certificates and the CMS will begin mailing out plaques and prizes. Teachers will be notified by email when the official results become available online.

Teachers can log in to their school accounts at any time.

Stay informed!
