Olympiad Entries

Purchasing and managing entries

Entries into the Mathematical Olympiad for Girls can be purchased via your Challenges Profile.

You will be provided with a question paper and 5 master answer sheets for each student, which will need to be downloaded and printed in school. We only send out hard copy question papers for first round Challenges.

You will also be provided with an online login for each student, which enables them to log in to the Challenges site after the Olympiad has been marked to see any feedback the markers have left.

Once your students have finished sitting MOG you will then need to upload their answer sheets to your Challenges Profile.

Download the Olympiad Handbook to help navigate you through hosting MOG.

Preparing for the Challenge

The problems on the Mathematical Olympiad for Girls are challenging and the olympiad is not suited to all students.

Students may be discouraged from participating in other Challenges if they are entered for the Mathematical Olympiad for Girls inappropriately.

Teachers can use past papers of the Mathematical Olympiad for Girls as a source of high-quality problems to encourage their students to think mathematically and to prepare for the Challenge.

We also sell downloadable past papers and books which can help with preparation.


Scoring rules for the Mathematical Olympiad for Girls are as follows:

  • Each question carries 10 marks
  • Partial marks may be awarded for incomplete or partially correct answers
  • One fully correct answer will gain you more credit than several guesses
  • There are no negative marks for incorrect answers


The top scoring students will receive a Certificate of Distinction or a Certificate of Merit depending on their score. The top 30 scorers will also be awarded a book prize; the title varies from year to year. Each student receives a Certificate of Participation.

Around 20 eligible top-scorers will be invited to sit the British Mathematical Olympiad Round 1.

The 2021 award thresholds were: To be released soon.
