CHEM 184: Do not take this professor unless you have the whole sets of old paper. He is too demanding. If you are taking one or two classes, it might be okay. But with three or four classes, you will fall behind within the first week and will never catch up with the material again. Exams are super-hard (You don't even know whether the problems are from 184 material.) and insanely long, making slow-paced people hard to pass. He will find anything to mark you down. His grading schemes are questionable too. I know some people got B's even though they did not finished their lab. He's one of those obnoxious people who takes the attitude that "life's going to treat you like shit so I'm going to treat you like shit - that way you'll be conditioned". This class was the most time-consuming class that I had at UCLA and ruined my transcript. Plus I came out learning nothing.
