Welcome
The Bebras challenge 2024-2025 has ended! Thank you all for participating!
Coordinators can now download the results and certificates. Students can log in again and see their scores and the correct answers.
As a Coordinator, you will receive an email in the summer when student registration for the upcoming school year begins.
We clean up the system during the summer holidays and delete all student accounts. You can download results or certificates from this year's competition until the end of July.
The USA Bebras Challenge tests your logic and computational skills through fun and challenging problems.
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. The difficulty of a problem determines how it will be scored. The scoring rules are as follows:
| Difficulty | Correct | Incorrect | Unanswered |
|---|---|---|---|
| A | +6 points | -2 points | 0 points |
| B | +9 points | -3 points | 0 points |
| C | +12 points | -4 points | 0 points |
