Gauss Mathematics Contests

The Gauss Contests are an opportunity for students to have fun and to develop their mathematical problem solving ability.

Visit our Coronavirus Information webpage for more details on the impact of COVID-19 on CEMC contests, workshops and resources.


All students in Grades 7 and 8 and interested students from lower grades.


Written in May. See details for current year.


The Grade 7 contest and Grade 8 contest are written by individuals and may be organized and run by an individual/homeschool, individual school, by a secondary school for feeder schools, or on a board-wide basis. More information for the organizing teachers is available.

More Details for 2021

  • Students can register through their school or as an Individual/Home School.
  • Schools can choose to have some or all of their students write on paper and some or all of their students write online. Schools do not need to provide the breakdown of online and paper participation to the CEMC in advance of the contest.
  • Students registered as Individuals/Home Schools will write online and will not be mailed any materials.
    Please contact us if you anticipate difficulties with this requirement.
  • Through their supervisor, each student writing online will be provided a link and a password to access a secure online platform assembled specifically for our 2021 multiple choice contests.
  • The Gauss Online Contest Platform will be open from May 12 to June 20.
  • Students writing online will:
    • Enter all of the information normally provided on the Student Information Form
    • Download (and print, if they wish) the contest paper
    • Solve as many questions as possible and enter their 25 multiple choice answers
    • Submit
    The recommended time allowed for completing the Contest is 60 minutes. The online contest platform does not track students’ time, so it is the responsibility of the Contest Supervisor to do this, if they wish.
  • All students will receive their results from their Contest Supervisor in the weeks after they write the contest. Students writing online will not receive their results immediately.
  • The Gauss Online Practice Platform will be available from April 12 – May 11, 2021 for anyone registered to practice using the online contest platform with the 2020 Gauss Contest problems. Please use the following password to log in: 2021Gauss
    • Please note that no scores will be generated for the Gauss Online Contest Platform. However, users can access the 2020 Gauss solutions on our past contests webpage.

Questions are based on curriculum common to all Canadian provinces.

Contest Registration Information

Register for contests through our website by the deadline. View fees.

Schools and Individuals/Home Schools that have not registered for previous contests are encouraged to participate, and can start by filling out either a New School Application form or a New Individual/Home School Application form.

Contest Preparation

We recommend that students spend some time preparing for our contests by trying to solve problems. Many teachers use past contests in the classroom and the CEMC problem set generator allows anyone to create random sets of problems with the option to customize the topics covered.

Results and Recognition

See the most recently available results booklet. Teachers may submit results and generate certificates.

We emphasize participation but also recognize top-performing students.
