Score Statistics

In mathematical problem solving competitions, it is  normal for your score to be lower compared to a typical school exam due to the level of difficulty of the questions. The median scores are often well below half the maximum points available for the competition. This is the case for the 2022 COMC, so we suggest you compare yourself to your peers through percentiles rather than the maximum possible points. The following tables should give you a good indication of your score compared to your peers:

Grade Top Score /80 Top Decile Scores /80 Top Quartile /80 Median Scores /80
K-8 73 55 43 22
9 78.5 50 36 22
10 80 51 40 26
11 78.5 53 42 30
12/Cegep 80 51 40 28
Overall 80 52 41 28

What to Expect Next

COMC 2022 Unofficial Solutions

The unofficial solutions are available for download. These will be replaced by the Official Solutions in January when the final results are announced.

Date and Time

The 2022 COMC was held on Thursday, October 27th in Canada and the Americas (anywhere in North/South American time zones), and on Friday, October 28th elsewhere in the world.

New for 2022: For those schools writing on Thursday, if your location is in the Eastern time zone or east of it, you will need to write the COMC in the afternoon, local time.  Those schools in time zones west of the Eastern time zone will write the COMC in the morning, local time.  For Canada, this means most of Ontario and east of Ontario writes in the afternoon, and Manitoba (and a bit of Ontario) westwards will write in the morning.

CMS Inclusion Initiative

The CMS is committed to contributing to a more inclusive environment in the mathematical community. Funding will be made available for students in Canada who identify as Black or Indigenous to participate in the 2022 COMC free of charge. For more information, please visit the CMS Inclusion Initiative page.

New for 2022: We are proud to have been able to provide funding in 2021 for a special Closing the Gap initiative for girls, however for 2022 we do not have the sponsorship for this initiative.


Normally, all registration is done by teachers or school staff through the Teachers’ Portal, which is where they also receive the results when marked.

Teacher Portal

If you have not submitted your final payment, please do so using the Teachers’ Portal.

Student Self-Registration

WARNING: This is only for those few students who need to participate but whose schools are not arranging their participation.

The CMS has arranged some in-person (not online or through Zoom) Open Writing Centres through our university partners. Space is limited and will likely fill up before the deadline of October 23rd. Spaces cannot be reserved except by paying the normal registration fee.  This is only available to students in Canada.

Paper exams - no online option this year

New for 2022: During the first years of the COVID pandemic, the CMS made arrangements to allow some use of “online” participation with Zoom (or similar) proctors.  This year, we are returning to all exams being written on paper by students under in-person supervision of a suitable proctor. 

Prices and Order Requirements

Prices are unchanged this year from 2021.  When placing orders, there is a minimum number of students per order, as indicated below.

Location Price per student Minimum Order size
In Canada $25.00 CAD 3
Outside of Canada $30.00 USD 8
