he thinks his answers is the one, no matter what you say to him he will stick to his answer, dont try to impress him with your new ideas, like his suit from 70S he wont pay attention to you.
I think most ppl in our class got at least an 80 so what you about not getting above a 60 is nonsense.
Almost impossible to achieve anything significant beyond 60% in his classes because he's so ambiguous.
He's cares whether you learn or not. Never gives a clear answer because he wants you to think about it. You have to take him even if you don't want to.
He thinks that he is better than you. He thinks he's always right, and he never gives you a straight answer to a serious question. He needs to be taught how to teach.
