Comment: He's an interesting professor but not particularly my style. Some may love him, some may hate him. If you study well before class, you'll do great!!! I sometimes didn't and it threw me off.

Comment: Professor Cohen gave very easy homework but his tests are just unbelievable. He like to talk about his research about atmosphere and even make questions about atmosphere, which I totally have no clue about. Don't expect that once you remember the whole textbook you can handle his test. It's never the case. Once you saw the questions, you just feel like you learned nothing...His lecture is interesting but still, you never felt you learned anything from him. Office hour not helpful as well. He is super smart, super passionate about research, super fun when doing experiment, but just not easy to get a good grade. Final is incredibly hard....hmmm

Comment: His lectures were much easier to understand than Whaley's, but that is probably because he lectures on environmental and basic physical chemistry rather than quantum mechanics. The lectures of his that I attended were decently interesting, but he would often spend too much time asking questions to the class and waiting until someone got the right answer. His problem sets were fairly straight forward, but his midterms were fairly difficult and the final exam had one problem in particular that was much more advanced than anything we had covered during lectures/homeworks/etc. The lab portion was also fairly easy and brought my grade up. The entire class is curved at the end of the semester, so don't be discouraged by bad midterm scores... My grade in particular was raised by almost 15% due to the curve!

Comment: Cohen generally seemed to care about his students, but would often ask poorly-phrased questions during lecture, then get angry when his students didn't raise their hands to answer them. In addition, his lectures were not always very interesting, and he didn't show too much enthusiasm except when he was lecturing on his own research. His midterm (the third) was reasonable, but his section of the final was quite rough, especially compared to Whaley's

Comment: Cohen was not a superb lecturer but he was better than Whaley. He was very helpful during office hours and you could tell he cared about his students and teaching well. The final exam had a problem beyond what we had done in problem sets but the class is curved.

Comment: His lectures were significantly easier to understand compared to Whaley, but his difficult exams made up for it. The final exam was brutal.

Comment: The final exam was crazy, it must've brought everyone's grade down by at 10 percent.
