Today I had a strange exam from chemistry. The teacher said: "In the next test I will not give you the questions, you will. You will pick 5 questions for yourself." Most of you will thinks that this is easy, but it's actually really hard. You need to memorize the questions and the answers. You can't pick questions like, "What is your favorite color", some guys did it last year, all of the failed. Thought I share this experience. Your thoughts.
