I gave a quiz in my precalculus class, I have two sections, each with 34 students. The first class took the quiz on Monday and many of them failed (14/34). I gave the same quiz to the other section on Tuesday and more than half the class earned 100%.
I think they shared the quiz with other students but I don't know how, they are not allowed phones and I monitor them during the quiz but it is impossible to closely watch all students at all times.
What do you think?
