Oh yes, I have one similar to that right now. Math, which has always been my best subject so it is really annoying. It is taught by this very arrogant grad student. We asked if we could have a review day, or at least a review sheet for our midterm (which is tomorrow and I'm completely stressed out) and he just flat out said no. BUT he said we'd be welcome to come to this certain building from 6-9 tonight while he's in his chess club meeting to ask some questions. HOWEVER, he was busy so he barely answered any questions. And whenever I go in for help he acts like I'm an idiot for not understanding. GRRRRRRRRRRR. The best part is all he really does is give us different mathematical rules, and explain the proofs. He doesn't give us any examples on how to use the rule in problems we'll be tested on because he says examples are "boring". I could go on and on.. I pretty much already have. He's just soo....
