Bauer was a good professor- his lectures were well-developed and covered all the necessary topics. If you understood his lectures, did the practice problems (problem bank posted on BruinLearn), and did the homework, you would be more than prepared for his exams. One thing I will say, however, is that Bauer either makes 2 hard midterms (averages 75) and a relatively fair final (average 85) or two easy midterms (average >90) and one hard final (average <75). Either way, I don't think it matters too much as long as you do your best to stay above the curve. Bauer was very clear at the beginning of the class that the average grade in his class will be B, so regardless of how hard/easy the exams are, you should just try your best to stay above the average.

I think that Physics 5B is harder than 5A because there is A LOT of content. However, Bauer does his best to answer questions and teach the material in a memorizable way. He also gives a formula sheet, which helps. I'd definitely recommend taking 5B with him as he's clear with his expectations and a fair professor overall.
