GHMS 2025 Bebras Computational Thinking Challenge
Thursday, November 13, 2025
Scores will be emailed out by the 1st week of December
The Bebras challenge is designed to help students explore their talents and passion for informatics and computational thinking with engaging challenges. Participating in the challenge is free and the tasks can all be completed without any preparation or studying. Students from 6 to 18 years old work through a set of tasks that focus on different topics and skills within informatics and computational thinking. They will have 45 minutes to complete as many tasks as they can, they are not expected to finish them all. The challenge has six different age categories with each their own set of tasks to keep things exciting and challenging for all students:
Kits (age 6-8)
Castors (age 8-10)
Benjamins (age 10-12)
Cadets (age 12-14)
Juniors (age 14-16)
Seniors (age 16-18)
Each group will get 3 sets of 5 tasks (except the youngest two groups, they will get 3 sets of 3 tasks and 3 sets of 4 tasks respectively). The 3 sets each have a level of difficulty: easy, medium or hard.
During the official Bebras Challenge, the problems come in three levels of difficulty: A, B and C.
The "A"-level problems are intended to be easier than the "B"-level problems, which are intended to be easier than the "C"-level problems.
You can find a problem's difficulty in the problem overview before you click on it. These categories all contain 5 tasks and they increase in difficulty. You start with 45 points and can gain or lose points as follows:
