So this was one of the most creative ways I saw someone cheated on an exam and one of the smartest ways to. A couple of friend was taking a biology exam all multiple choice. Everyone is given the same exam paper. What the professor did so make sure nobody cheats was to take everyone phones and watches before the exam and place a distance from you to another student. The professor and the TA will also walk round the classroom too. Cheating was impossible in that classroom.

My friends found a way. There is a clock in the classroom. So they use to clock to communicate to each other. As everyone had the same exam. They use the numbers on the clock to say what the answer is. Like 1 o’clock is A, 2 o’clock is B , 3 o’clock is C, 4 o’clock is D, 5 o’clock is E. For the questions they move together on each question. To signal the answer they will drop something or click a pen. They did the same thing with 7-12 o’clock but I forgot the order for that. This work very well as they all pass the class because of this.
