Professor Kang was one of my better physics professors I have had so far at UCLA, having taken the intro physics 1 series courses. Broadly, he's a great guy who clearly professes his concern on student well-being and learning, and it's very evident. He's also extremely nice and willing to listen to student concerns, but I can say that personally he was not very engaging as a lecturer.
First, N.B. that the class does require the use of Mastering Physics, which is where all of your homework will be assigned. For us, due to COVID-19, our final exam was held on Mastering Physics as well. There's homeworks every week, usually around 7-10 MP questions taken from the textbook, so the workload is very consistent. The grading breakdown is originally as follows, but due to declining lecture attendance, Professor Kang decided to hold these short quizzes (to check for participation) that might've changed the following grading scheme:
1% - Course Evaluation
3% - Discussion
16% - Mastering Physics Homework
20% - Midterm I
20% - Midterm II
40% - Final Exam
Following up, Professor Kang gave us advance notice of the participation quizzes, and it was simply a google form where you filled out your name and some simple conceptual question (what's great is that as long as you answer, correctly or incorrectly, you get full points for participation). Discussions are held similarly. We switched formats throughout, but settled on this: doing a discussion worksheet [in groups] for the first 10-15 minutes, before the TA (mine was Tadi) would give a review of that week's material, followed by more discussion worksheet time. As long as the worksheet wasn't completely empty, and you gave honest effort, you were getting a 100% for discussion grades.
The reason Professor Kang gave us lecture participation quizzes was because he "feels more motivated to teach with more students in the lecture room". He really does care that students show up and are giving effort, which is something that he looks for in students. He basically begged everyone multiple times to show up to his office hours, and pleaded with us to use the google form he created where we could send in feedback about the class and make any comments. He proclaims himself as the "captain" of our ship, and because he's our "captain", he's always on our side. He posts preliminary lecture notes and finalized lecture notes on CCLE, for those who couldn't read the board or hear his soft voice, but honestly even up front his lectures just aren't very engaging, and it's not for a lack of effort on his part. As a student, I really appreciated how much effort and how serious he took his teaching responsibilities.
Overall, I wouldn't say that he cemented in the material extremely well, but it's pretty standard. What makes him great is more his other aspects, essentially how much he cares about student learning and wellbeing, and that he genuinely is trying to help everyone do well in his class. Given how considerate, kind and thoughtful he is, I would say that Professor Kang is definitely worth a shot for Physics 1C.

Kang was great! Very nice and understanding teacher, decent lecturer. Fair grades and exam problems (often similar to practice test problems, or ones from years past as well if you can find them).

Professor Kang is awesome and, of course, the best physics professor I have taken at UCLA. I love his way of presenting the materials which is full of logic. He also likes to provide historical background on how the physics theorems were developed over time, which is so stirring because you witness the born of a historical moment when the final formula appeared before your eyes.

Actually just try follow the lectures and do the homework carefully- this is enough for preparing for exams. The homework, quizzes, and midterms/final are all fairly assigned and graded. Frankly speaking I did not spend a lot of time in this class, I pretty much believe the key in here is to try understand those physics concepts instead of just memorizing the formulas. Take Zhongbo's 1C, making you healthy and happy.

Prof. Kang is such a nice and caring professor. I HIGHLY recommend taking his class. I have had a really rough time with 1A and 1B but everything began to make sense in his class. Other professors in the physics department have a god complex but Kang does not. He is willing to help, and really does not want to give you a bad grade. He has an anonymous tip line to give him feedback and he really tries his best to adjust to the students needs. The only complaint I have is that I took a discussion in the beginning of the week, but I suggest you sign up for a Thursday or Friday discussion because the worksheets in class were often subjects we had not yet covered.

Overall, this class was a pretty average experience. Boring lectures, fair exams, and hit or miss TAs. Professor Kang is a really nice guy who goes out of his way to help students, but physics at UCLA is just so hard to learn from lectures alone. Personally, I invested about 10-15 hours a week reading through the textbook and taking notes, which really helped me develop intuition for E/M and optics.

Both midterms were fair, although 1C is a naturally hard class so you still need to study a lot to do well. I thought the first midterm was fairly straightforward, but the second was a lot harder due to a time crunch and a couple of tricky questions. The averages were pretty high at 84 and 78, respectively. Under normal circumstances, I would expect the final to be difficult, but Kang turned ours into a Mastering Physics problem set due to COVID-19. It was very easy (median 100%!), which inflated grades a bit.

Overall, I would take Kang again because I learned E/M and optics pretty well without suffering through Corbin's exams. Although I'm a Civil Engineering major, I found 1C to be really interesting, specifically Maxwell's equations and special relativity. If you allocate plenty of time to learn the material outside of lecture you should do fine.

Kang is the best Physics professor I've had at UCLA. He genuinely cares about student's learning and our grades. The tests are very fair, and it's easy to do well in the class if you keep up with the homework and textbook. I definitely recommend taking him!!

He was probably the best physics professor I've had at UCLA. He genuinely cared about his student's learning and that was really clear ever since the first week. He is a clear lecturer, but not the most engaging. He also spends a lot of time during lecture deriving equations but it would've been way more helpful if we actually did examples/sample problems in class. The midterms were really fair and the averages were pretty high both times. The final exam was easy too but it was open book and open notes, so the circumstances are a bit different. Overall though, I would recommend having him for any of the Physics 1 classes.

Extremely helpful professor Zhongbo Kang! Lectures are clear and he is always willing to help students and very caring. Tests are fair and he takes you effort into account! One of the best physics professor.

Not particularly memorable - completely average professor. He started off with powerpoints and later started writing down notes. Tests average difficulty and we had weekly mastering physics homework. He was pretty nice and explained nicely but nothing in his class particularly stood out.
