Your classmate asks you to pass him your answer sheet in the?
No, never. If the exam is held in a hall and not just a quiz in class, being caught cheating could seriously impact my future, and I will not risk that. Hes not worth it. If it were a friend, I might have helped him study, and shared my notes, but thats not cheating. In an exam, you sink or swim on the basis of your own merit, not that of your classmates.
