I would give people the benefit of the doubt. Do you know anyone who would cheat? I don’t know anyone who would do it. I know about 10-15 people who have taken exam 9 at the end of the window. I would be shocked if anyone cheated. Sure, this is a small sample size, but I don’t think people would risk it. Especially, since these people have gotten to their last exam. Maybe I am being naïve.
