I remember professors doing that kind of things when I was a student then declaring that students didn't studied well, didn't followed their rules, cheated, or anything else. I don't think it help students to progress it any way. It just feel like you are fighting against a bureaucraty which has no rules, or which has rules that will only be revealed until it's too late. What they are creating is traps, and traps don't teach anything because they are random. Please teachers, read Richard Feynman stuff, he had such a joy to teach his students and stop bullying your students.
