You like logical thinking and do not shy away from mental challenge? You would like to get to know mathematics from a different perspective and meet new people with similar interests? Then you are exactly at the right place! Every year, we at the Mathematical Olympiad organise numerous events as part of a competition with the aim of bringing together young people like you from all over Switzerland to share our passion for mathematics with you. With us you will get to know mathematics in a completely different way than at school. The logic, elegance and joy of the subject are at the core of our attention, not memorization or tedious arithmetic. We are looking forward to welcoming you at our next events!

First Round

The first round of the Mathematical Olympiad takes place online every year in September. You have the whole month to register on our website and solve the 35 problems of the first round during 75 minutes. It may even be that your entire school class participates and writes the competition together during school hours.


In the first round you will be confronted with problems from number theory, combinatorics and geometry. The questions require almost no previous theoretical knowledge and are mainly about creative and abstract thinking. You can read more about the topics and style of the Mathematics Olympiad here.

Conditions of Participation

You can participate in the mathematical olympiad if you...

  • are born on 2 July 2001 or later.

  • are not yet studying at a regular university.

  • meet one of the following conditions:

    • You are attending a school (e.g. grammar school, cantonal school, upper secondary school, vocational school, ...) in Switzerland or Liechtenstein

    • You are attending a Swiss school abroad.

    • You are attending military school, civil service or civil defence.

      Exceptions, if none of these conditions are met, are possible. Please contact us in advance at info@

  • are not participating in a foreign Mathematical Olympiad in the same year, which also serves as a selection for the International Mathematical Olympiad.

Second Round

The second round consists of three preparatory meetings and a subsequent examination, which all take place simultaneously in Zurich, Lausanne and Lugano. At the meetings you will get to know the organizers and countless other participants and together we will prepare for the upcoming competition. You will receive a theoretical introduction to the three topics number theory, combinatorics and geometry as well as useful tips for the exam. We will also discuss many interesting examples and you will also get a lot of time to give the tasks a try and exchange ideas with other participants.


The exam of the second round will take place at the beginning of December on a Saturday. It lasts 3 hours and consists of two tasks per subject area, so there are six tasks in total. After the exam you are invited to an aperitif in front of the exam room. You will receive more details about the meeting point and time by email before the events. The exact dates for the current year can be found here.


If you do well in the second round, there are still many great events ahead of you. The criteria for qualification are as follows:


  • The top 25 participants at the second round qualify for the final round.

  • The top 16  participants at the second round who are under 16 years of age on July 1 and have not qualified for the final round will qualify for the JuniorCamp.

  • The best 4 participants of the second round qualify additionally for the EGMO.

Final Round

During the final round we will organize further meetings and a training weekend, which will be used to prepare for the finals in March. The final exam will take place at the end of a one week camp, the highlight of the Mathematical Olympiad, where you will get to know the other finalists and the organizing team and we will have a lot of fun together. The 12 best participants are awarded medals, usually 2 gold, 4 silver and 6 bronze medals. The awards ceremony will take place at the beginning of March during the MO-Day at ETH Zurich. Those who have been awarded a medal also qualify for the selection round, in which they compete for places at international events.


The JuniorCamp takes place every year in June and consists of a weekend where we pursue different mathematical topics and have fun with mathematics. The aim of this event is to support young students who have not yet qualified for the final round and to prepare them for the competition next year.
