The Bebras Challenge is a computing challenge. There are a series of challenges scaled from very difficult to very easy. I was in the top 25% of my class.

I enjoyed the challenge called gifts where you had to show who gave gifts to who. In the lines between each person you had to decide if they received a present or if they gave a present to a person next to them. I enjoyed this challenge because of the process of elimination aspect it had. I thought arrows one was difficult. The directions explained that a black arrow must point at a black arrow and a white arrow must be pointing a another white arrow. I thought it was difficult because I did not know an arrow could point through an arrow of the different color.
