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 |
