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 11. October 2020 23:59 UTC+0.

2. Pre-Final Round

Participants that have solved the qualification round successfully are qualified to participate in the pre-final round. The problems will be more challenging, but even more interesting!

Problems and Points
The pre-final round consists of 10 problems that vary in difficulty, points, and topic. All topics from geometry to number theory are included. There are three types of problems that give you two, four, and eight points:

It is possible to reach up to 40 points in total. Students have to reach at least 20 points (under 18 years) or 28 (over 18 years) to qualify for the final round.

Process and Submission
All participants that are qualified and that are registered for the pre-final round will receive the problems via email or at the online status page on Monday 9. November 2020. From that day on you have one week until Sunday 15. November 2020 to solve as many problems as possible! You can submit your solution online via a special submission form: You can choose if you would like to submit the solution as handwritten version or as computer typed document. We recommend to write the solution in the blank sapce on the problem sheets of the pre-final round. Please highlight your final solution for each task. However, computer typed versions do not receive a special note on their certificates.

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 for which students have 60 minutes time.

Exam and Points
The final round consists of a single exam with 40 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
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 40 minutes exam between Monday 7. December and Wednesday 9. December 2020. 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.
