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 2019 COMC!
