Though sometimes the explanation are a bit abstract and hard to understand, but he's accessible outside of class, so I can still understand most of the contents. Also, the homework and test have reasonable difficulty, which the class is enjoyable.

Excellent professor! Occasionally went a bit slow in lecture, and the homework was much harder than the quizzes or exams.

Great professor, not much else too say. You should expect a lot of work is Physics 20 series regardless of the professor.

Does not give the most clear answers to your questions. Pretty chill dude and his lectures were pretty good imo

(I had her for 100A which isn't listed on here) Dr. G is a lovely person but her lectures are absolutely impossible to follow. She spends the whole class time doing proofs at lightning-speed, and never does any examples. It's unclear what material is important to know for exams. This was a very rough transition to upper division physics for me.

Great teacher. Lectures are really good at covering the base of information, but strong understanding of the textbook and homework is necessary to do well. She will at times skip over essential formulas and necessary examples, so be sure to read the book. Overall a great professor
