Professor Weld sticks to the textbook and the lectures are all right. The final covers everything over the quarter so it is overwhelming. He would put some harder versions of the typical problems which is fine. But there are always a few thinking problems that make his exams unpredictable and hard if you don't know all of the material indepth.

He can be very dry but very funny during his lectures. He is very passionate about physics so lectures can be very interesting but he can be monotone at times which can make them boring too. There are very few homework assignments and he doesn't provide study guides or practice for exams. Be ready to study on your own. Otherwise, he is great.

One of the hidden gems in the physics department. Can be dull at times in lecture, but makes up for it with his jokes. His homework is challenging but exams are straightforward, especially since he allows a cheat sheet. He has a strong understanding of EM, which is exemplified by his clear lectures and adeptness at responding to student questions.

Overall the lectures are easy to follow and well prepared. However, the inconsistencies between homeworks and exams are frustrating. In the homework that was due a day before the midterm, there are ~5 questions on stress tensor, but there were none on the midterm. Similar things goes for the final.

As far as physics profs go, he's pretty good. Lectures are clear and we follow the chapters in the book pretty closely. The material is difficult, so definitely go to office hours when you can, sometimes he will help you get started on a HW problem. You are allowed a cheat sheet on exams which is a lifesaver!

One of the best professor in the physics department in teaching. He knows the content pretty well and can provide great physical intuition and many real-life examples. Have taken his 115C in the fall, which was also delightful. Homework and exams are not hard. This means this course is relatively less stressful. In general, I strongly recommend.
