Once we had an exam, 50 MCQs in 1 hour. I did not study for it and thought I would fail. I was scratching my head when suddenly I realized a girl in front of me had her answer sheet visible to me. The seating arrangment was such that the the row immediately in front was lower than the one behind. So I was sitting behind the girl and she was in front slightly lower. I just pretended that I read a question and then I would pretend I was thinking too hard by frowning and looking up, then within a second I would see the answer to a question from her answer sheet. I kept doing this. At one question, I felt the girl was wrong. So I answered differently. And guess what? She got 36 marks, I got 37. heheheheh
