YTA. My boyfriend told me last semester that he had a professor give out a horrible exam that she didn't prepare the class for at all. The next lesson after the exam, the entire class reamed her for it. When my boyfriend stood up to speak his peace, his professor said that he shouldn't be talking since he (accidentally, btw) didn't do the entire last page of the exam. She said that in front of the entire class. I don't know how big it was, but that doesn't matter. The only people who have a right to see their grades and work is the student and teacher, embarrassing them with grades is only going to get you some pissed off people, nothing actually positive.
