1. Qualification Round

The qualification round is the first stage and consists of five math problems: A, B, C, D, and E. These math problems vary in topic, difficulty, and subject. The problems range from geometry to number theory to make sure that everyone finds interesting problems to work out:

The problems will not only sharpen your mind but also challenge your math skills! All participants of the qualification round will receive participation certificates. You need to solve at least three problems (under 18 years) or four problems (over 18 years) correctly to qualify for the pre-final round.
The submission deadline is Sunday 17. September 2023 23:59 UTC+0.

3. Final Round

Participants that have solved the pre-final round successfully are qualified to participate in the final round: a multiple-choice online exam with 20 questions.

Exam and Points
The final round consists of a single exam with 20 multiple-choice questions involving mathematical calculations and knowledge. The questions require math skills as well as knowledge about mathematical definitions. Finalists have 60 seconds for each question! To every question there are four possible answers given (only one is correct). A correct answer equals one point. The awards and prizes are given to the finalists with the most points in the final round.

Teacher Registration or Recording
The exam will take place in the school of each finalist supervised by a teacher. All finalists have to select a teacher who agrees to supervise the final exam. We will send all required information to the selected teacher who has time to conduct the 20 minutes exam on Tuesday 14. November 2023. The teacher has to make sure that the finalist does not cheat and does not open any other browser tabs, websites, programs, or computer windows during the exam. Participants can also record their exam with a video camera or smartphone and upload the video. In this case, no teacher is needed.
