CMO Qualifying Repêchage Competition

The CMS wishes to thank the sponsors and partners who make our competitions programs successful.

The Canadian Mathematical Olympiad Qualifying Repêchage (or just “Repêchage”) is an annual competition that serves as a qualifier for the Canadian Mathematical Olympiad (CMO). It typically runs at the beginning of February each year, shortly after results of the Canadian Open Mathematics Challenge (COMC) are announced.

Participants in the Repêchage receive a set of problems whose solutions must be submitted within a week of receipt. The Repêchage is a take-home competition. The solution papers returned to the CMS are carefully reviewed, but not explicitly scored.  The students who demonstrate the most innovative, clear, and complete solutions are invited to the CMO and the others are thanked for participating. There are no other prizes or certificates for participation.

Save the Date!

The 2023 Repêchage will be held from February 1st to 8th, 2023.

2022 Competition

The 2022 Repêchage results are in!

  • 74 students were invited to write
  • 65 students registered and submitted their work
  • 16 of these were advanced to the CMO and another 17 were advanced to the CJMO.

All competitors were contacted by email to inform them of the results.

Successful competitors will receive an invitation to the CMO in early March. Competitors who performed well but did not perform well enough to earn an invitation to the CMO and who are in grade 10 or younger will receive an invitation to the CJMO.

By Invitation Only

Students who participated in the COMC and did well, but did not qualify for the CMO are invited to write the Repêchage. Approximately 75 students are invited to write the Repêchage. Based on the results, roughly 20 of these students are selected and invited to participate in the top national math competition: the Canadian Mathematical Olympiad (CMO).

Eligibility

Students invited to write the Repêchage must complete a declaration that they meet the eligibility requirements to write the CMO. The CMO Eligibility Requirements are listed on the CMO page.

Preparing for the Repêchage

In addition to the past Repêchage test papers, students are encouraged to use past COMC and CMO papers to help prepare for the Repêchage. The CMS also has many problem-solving resources available for competitors.
