There were things on the final that were never covered in lecture, only specific parts of the book. You will be doing a lot of self teaching and TA's cannot always answer questions. His office hours were not very helpful either, basically would just give you more problems to try without explaining.

While he tends to be very 'mathy' in his explanations, reading the textbook helps a lot and his office hours were good too. Note that many of these reviews are skewed because he teaches 21 which tends to be a weeder course. He is a nice guy who wants you to succeed, you just need to do your half of the deal

Professor Sherwin is clear with expectation, and cares very much about his students' success. That being said, he is rather disorganized with lectures, is not very good at answering questions during lecture, and mostly reads out of the textbook with few alternative explanations. Midterm and final were fair and nothing too crazy.

He had clear expectations, and, yes, he requires homework drafts, but it's to show that you tried before potentially looking up answers. (allowed) He had us read the textbook sections before lecture, which helped. We did learn the momentum flux unit on our own, which was not ideal. Although the final was definitely difficult, each problem was fair.

Sherwin clutched up for me big time; he let me to switch into the class late even though it was full and it saved my life because it isn't offered in the spring. He cares about his students and wants them to succeed, even though he is a little disorganized and doesn't answer questions very well. Tests have very easy and very difficult questions.

Had a high A until the final that had a 67% class average tanked everything which was upsetting. I think there are some downsides to phys 21 that are out of Sherwin's control so I can't really blame him but I studied really hard and still got a low B. tbh the concepts of this class are not that hard but the way its taught is which is annoying.

Homework and textbook are really hard but doesn't seem like something Sherwin can control as every prof seems to use the KK book as standard. He wants students to do well and if you like physics enough to attend office hours and study you'll be fine grade-wise. His exams are very reasonable considering the material in the textbook is hard.

I can see that he has good intentions, but I do not think he is fit to teach this subject. I'm sorry to say it, but he is too slow in class, he gets confused at things he writes down, and he often cannot answer your questions. He also sticks to the (confusing and poorly written) textbook too often, in my opinion.

Professor Sherwin is an excellent professor, he knows his stuff, but this class is difficult. I took this as a non-physics major (I still don't know why), and it was really hard. If you're taking this class, I can't stress enough how important going to lectures and going to office hours are---I regret not going to office hours more often.

Swear he doesn't know what he's talking about and just copies the textbook onto the board any question asked he just says random stuff that doesn't answer it. Also rough drafts for homework is so annoying and incredibly dumb, takes up so much time for no reason then he also grades them incredibly meticioulslcy like it's not just homework.

Way too much work for a 4 unit class, 20 hours a week is insane and he wants rough drafts for physics homework?!?!?!

made me debate not being a physics major fr

Do not recommend. Class was difficult in both material and grading.

Not chill

Exams are really hard and has nothing to do with the practice exam. Lecture is just basically copying the book on the broad. Professor Sherwin seems so concentrated on the blackboard that if you raise your hand, usually it will take 1-2 minutes for him to notice you. My entire PHYS 21 is basically self studying.

Professor Sherwin may have a slow, sometimes confusing lecture, but his office hours were very helpful. He's kind and really wants you to succeed. Tests were not hard and covered all of the material in a way that made you think, but won't make you struggle. Also, reading before lectures were CRUCIAL for success on quizzes and exams.

I found it difficult to follow professor Sherwin's lectures. I don't think he explains the concept very clearly. But I guess that is because he focuses mainly on his research so he usually thinks about the concepts in more difficult/abstract way. That said, this class was okay. The exams were challenging and fun.

He talks really slowly, covers material really slowly too. But he is super nice and always willing to help :) If you try in the class the curve can get you above a B.

Sherwin's lectures could be confusing at times, and he didn't really understand questions. Homework was difficult, as were tests, but not especially so for the 20 series. Not the greatest professor, but still an interesting class.

he just wrote the formula on the borad during class without explaining. hw is difficult also the test. hard to get high grade.

what can I say He never seems to dig into the equations and just write the formula on the blackboard. You can barely understand what he says. You need to a lot of reading if you want to fully understand what the formulas come from.

He did not seem confident at the board, would forget things in the middle of explaining them. He was a good guy, but not a good teacher.

very awkward person, always smiling, doesnt has good intentions but cant level down to his students for undergraduate level physics

He has demonstrations almost every class, which are really cool and help you to understand the material he is teaching that day. Sometimes he talks very slowly and ambiguously, kind of like how he writes: with a lot a things scratched out like he started to say something and then decided to say something different. But he knows his material
