If you are like me who is just checking a box on my DARS, don't bother taking this class. Professor Bauer is a sweet guy and he wants us to really understand what's going on behind the scenes; however, he writes out a formal derivation for every major formula unlike my current professor, professor Hauser, who is happy to let us use formulae to crack physics problems.

TLDR: You'll be fine with Professor Bauer!

After having taken Physics 1A with Professor Frieman, Physics 1B with Professor Bauer was great. Physics is physics and you should expect a certain level of rigor of course, but this class is very doable.
Homework is only Mastering Physics which I recommend doing. It was pretty close to the difficulty of the midterm questions.
In my opinion (as a non-physics master or even enjoyer), both midterms were veryyy straightforward and clear. No confusing stuff or crazy derivations. In fact, if you think about the questions hard enough, you'll see that Professor Bauer is typically giving an easy trick question. For example, you might initially think that you have to do some long calculation, etc., but in reality, the answer might be stated on the question already. Stuff like that. So I highly recommend grasping the concepts and not just doing the homework for a grade.
Attendance is required for the discussions, but you can miss two I think. The discussion worksheets were super hard, but I never encountered them on the exam or anywhere. Good thing they are graded on completion/some work shown.
My only thing is that the final was kinda hard. Like I sat there for the first 30 minutes and I was like damn I don't know what to do. Anyways, it got graded and they were pretty generous with the partial credit so I still ended with a B in the class.

His grade cutoff is very generous. A is 93, A- is 90, B+ is 85, B is 80, B- is 75, C+ is 70, C is 65, C- is 60, D+ is 55, D is 50, D- is 45, and F is <45. No curve, but I think the cutoff is good enough.

Also lol he wore the "Tax the Rich" sweater, one lecture that was funny. If the previous statement is in any way incriminating, for legal reasons, it is a joke and he never wore that.

Professor Bauer is a clear lecturer, and his lectures are pretty helpful. He spends a lot of time doing derivations and goes into depth about the material. He speaks at a good pace. He is super helpful during office hours, so if you get stuck on homework, I would recommend going, as he does a good job of working the problems out. His homework is just Mastering Physics and pretty reasonable. Required discussions, with like 2-3 dropped discussion attendances. His tests are reasonable, not the kind involving tons of derivations or tricky calculations, exams where you can expect to get 90-100% if you understand the material thoroughly. He did not curve the class, but we ended up with around 30% A+/A/A- and 35% B+/B/B-. I would probably take this class again.
