The qualification round is the first stage and consists of five astronomy problems: A, B, C, D, and E. These astronomy problems vary in topic, difficulty, and subject. The problems range from knowledge skills to astrophysical calculations to make sure that everyone finds interesting problems to work out. The problems will sharpen your mind and also challenge your science, math, and astronomy skills!
Points and Submission
Each of the problems can give you up to 5 points and there are 25 points in total. All participants of the qualification round will receive participation certificates regardless of the results. You have to score at least 15 points (junior, under 18 years) or 20 points (youth, over 18 years) to qualify for the pre-final round.
The submission deadline is Friday 26. April 2024 23:59 UTC+0.

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 six different problems that vary in difficulty, points, and topic. There are three types of problems that give you four, six, and eight points:
- 2x Basic Problems: The pre-final round includes two basic problems (lowest difficulty). A correct solution to a basic problem adds four points to the total score.
- 2x Advanced Problems: The pre-final round includes two advanced problems that are more difficult. A correct solution to an advanced problem gives you six points.
- 2x Research Problems: The pre-final round includes two research problems: These problems require you to read two short scientific research papers and to learn about recent scientific results in order to solve the problems or questions. This will give you the chance to get in touch with scientific research while solving the problems.
It is possible to reach up to 36 points in total. Participants have to reach at least 18 points (junior, under 18 years) or 24 points (youth, over 18 years) to qualify for the 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. The questions require knowledge about astronomy and astrophysics. 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.
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.
