I have not looked at physics since it was entirely online in high school and I didn't remember anything so I was very afraid of taking physics in college, but Professor Tung was awesome. His exams were mostly fair and even when one was particularly hard he was very accommodating and receptive to student feedback which I really appreciated.

Tung's class was an interesting experience for me, as it broke my 4.0, however, I can't say that it was a bad class by any stretch of my imagination. He's a solid lecturer who kept me engaged, and he provides a littany of resources for you to study. That being said, his exams are brutal. The first one was no sweat and realistically its all basic algebra, but from the second exam on, it gets crazy. His questions are super in depth, and we were given nothing like it to practice for the class. He's also the only professor that doesn't use Mastering Physics in the 5 series, and instead uses Kudu, which has no problems that will accurately prep you come exam time. He still was a caring professor though, so I can't say too much bad about him

this class was so hard. For summer it was an online 6 week class, with homework assignments and weekly kudu quizzes and an online final at the end (because of the hurricane quizzes 2 and 3, and 4 and 5 ended up being combined). Lectures were streamed on YouTube live and Tung is more focused on derivations than showing how to solve problems (although to be fair this has been my experience with all the UCLA physics profs I've had). The kudu quizzes were so hard not necessarily because the questions themselves were super hard but because they were a time crunch (I suspect to prevent people from cheating), so if you made a mistake in one of the questions you would not have a lot of time to go back and redo it. The final was also difficult and nothing like the kudu homework assignments or quiz questions. Class got up curved pretty heavily at the end, and Tung still had his policy of 65% required homework and anything extra is extra credit though so I can't complain too much. if you like physics you should be fine

I enjoyed Tung's lectures. Material is definitely difficult, but if you are attentive in lecture and keep up with all of the practice problems it isn't too bad.
