Beren was one of the best prereq chemistry professors I took. He was very approachable for office hours, not only because he made sure everyone didn’t have a time conflict. He was VERY clear when reviewing the class material.

It's Beren. Chances are, you gotta choose between Beren and Baugh. I don't even have to write anything else. Choose Beren.

Beren was very considerate considering whole coronavirus situation and the sudden switch to online learning. The notes that he put on CCLE were very organised and really helped with understanding his lectures, which were also very organised. His exams didn't throw out any curveballs; as long as you studied the material, did practice problems, and understood the concepts, I think you should be fine. For this quarter, all of the exams were take home and we had about 48 hours to complete them, which is definitely more lenient than during normal chem 20B classes, so that might be something to keep in mind but overall I really liked this class, which is saying something since I hated chem in high school :,)
