The USA Bebras Challenge tests your logic and computational skills through different types of 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
