The problems vary in topic and difficulty: Some of the problems test your astronomy knowledge, others require calculations. The qualification round will not only sharpen your mind but you may also learn more about astronomy and astrophysics!

All participants of the qualification round will receive participation certificates. 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. Digitally typed solutions receive a special honorary note on the certificates.

The pre-final round consists of 10 different problems that vary in difficulty, points, and topic: 4x basic problems (four points), 4x advanced problems (six points), 2x research problems (ten points). It is possible to reach up to 60 points in total. Participants have to reach at least 30 points (junior) or 45 points (youth) to qualify for the final round.

All participants that are qualified and registered for the pre-final round will receive the problems on Monday 6. May 2019. From that day on you have one week until Sunday 12.
