Euclid Mathematics Contest

Written by over 20 000 participants worldwide every year, the Euclid contest gives senior-level secondary school students the opportunity to tackle novel problems with creativity and all of the knowledge they've gained in secondary school mathematics.

The contest’s mix of short-answer and full-solution questions provide participants with an opportunity to effectively communicate their thinking. Additionally, the final questions in the Euclid are some of the most complex and challenging among all our contests, helping participants build perseverance, a key component of mathematical problem-solving.

What is the Euclid Contest and why participate?


  • Students in their final year of secondary school or CÉGEP students
  • Motivated students in lower grades


Written at school in April. Visit Our Contests for dates and deadlines for the current year.


  • 10 questions; a mix of final answer only and full-solution
  • 2.5 hours
  • Score out of 100
  • Marks are awarded for completeness, clarity and style of presentation. A correct solution, poorly presented, will not earn full marks
  • Written at school, participants write individually and on paper
  • Some calculators permitted

Mathematical Content

Most of the problems on the Euclid are based on curricula up to and including the final year of secondary school. Some content might require students to extend their knowledge.

Practicing with past contests is a great way for participants to get to know the style of questions that appear on the Euclid, as well as common topics. Participants can access our updated preparation materials which are specifically aimed at the Euclid contest. They can also learn or refresh specific topics by reviewing our Grade 12 open courseware.

Contest Supervision

  • Contest Supervisors should arrange to have participants write the contest at school and are responsible for ensuring that participants are supervised appropriately.
  • Once the contest has been written, all of the contest materials should be returned to the CEMC in one package for marking.
  • Results will be available in the Contest Supervisor Portal six to eight weeks after the contest date.
  • Visit Contest Supervision to learn more about what's involved in supervising a CEMC contest.
