I took this class during the corona quarter as well so please keep that in mind.

Here's a breakdown of the class:
10% HW
15% Lab
20% MT1
20% MT2
35% Final

Jiang's lectures were pretty dry (perhaps because I wasn't that interested in the material), but I think he explains things pretty well. He recorded his zoom lectures so I ended up watching them on CCLE at a faster speed. He kind of has an accent if that bothers any of you at all, but it didn't make that much of a difference for me.

He did open note midterms on MasteringPhysics with 4 multi-part questions. Each part had 3 tries and if you did the homework he assigned and maybe the problems at the end of each chapter, you were pretty much set to get a 100. The homework he assigned each week was usually 7 or 8 mastering problems which were pretty easy if you a) went to lecture or b) read the book. I personally didn't take the final because of everything that happened at the end of this quarter, and he was kind enough to let us take an optional final. I looked at the final and it wasn't too bad as long as you paid attention in class and did the practice final he sent , but I was thoroughly checked out by the end of spring so it looked hard to me.

Anyway, Jiang is a really sweet professor

Honestly, I felt pretty mislead by the previous reviews and the grades that were posted on here. The midterms and homework are fairly easy and doable to get good grades in, but I, along with many other students, were taken aback by how difficult the final exam was, which was worth 35% of our grade. We were given no extra practice exams or discussion problems, which made it harder to prepare for the final exam; Prof Jiang just said to review the Mastering Physics homework problems in order to review, but we were only given 7-8 problems per week, and these were the same ones we used to review for the midterm. So really it was just recycling the same few problems, and we weren't able to apply the concepts in a different manner to adequately prepare us for the final. I really felt blindsided by the final and if you have the option to take this class with someone else, I would.

I felt like I learned a lot better from doing the weekly homework and TA review worksheets than actually attending lecture. Lectures were often very theoretical-heavy, and while that's great for people who are actually interested in physics, I found lectures to be boring and not really worth my time if half of each lecture is not going to be on the exam. I'd still recommend going to lecture though because occasionally he'd mention certain things to focus on for the next exam, plus his lectures are NOT recorded (though he does post handwritten unorganized lecture notes).

For exams, definitely review some of the problems he went over in class, something I honestly failed to do. Also remember to write down all the equations necessary on your cheat sheets (you get one for each exam) since this class goes HEAVY on using the right equation. His exams did get harder and harder over the course of the quarter so you'll want to do your best on the first two exams. ALSO don't be afraid to ask for a regrade if you think you deserved a point because that point may or may not break your grade at the end!!

If you are thinking about taking this class with this professor, RUN. This professor has been the worst professor that I have ever had at UCLA. I read the good reviews for this prof before enrolling, but they all had to do with his policies during covid, which are completely different.

This professor DOES NOT RECORD LECTURES, and HAS NO EXAM PREPARATION. His exams require an unrealistic MASTERY of the material, which can't be done within a reasonable amount of time. He offers no makeup exams either, so good luck if you have an emergency. Midterms are 20% of your grade, and the final is 35%, he doesn't offer a midterm drop policy. The grading also takes FOREVER. The midterms allow one page of notes, but none of it will help because the content is twisted in ways that require a mastery of the material. I copied down every single formula, chapter summaries, diagrams, and every mastering physics problem onto a single page and could only scrape by with a 73% on the midterm.

Jiang mutters frequently during lecture and the writing on his ipad is extremely difficult to read. It can be difficult to understand him at some points in the lecture. He does upload these "notes" to canvas, but they are so illegible that it's not worth your time. No campuswire is set up, and the mastering physics only allows 5 attempts per problem.

I already know there's going to be a lot of people defending Dr. Jiang in here. The people that do are people that study all the time, or are only focusing on this class and have a light workload. If that's the type of person you are, fine, take the class and find out for yourself. For the rest of the people that are managing other classes, or don't have the privilege to study all the time, save yourself the stress and don't take this professor. Or take it and find out exactly how bad it is. You'll regret it though.

Took jiang in fall 22. He did not bruincast, opting instead to post notes that were messy. He did not make a campuswire/discussion forum or anything, meaning -- good luck asking questions if you couldn't make office hours. For midterms he would always tell us to just review the mastering instead of giving us practice problems. This worked out for midterm 1... not so well for midterm 2 and final, which IMO were beyond the scope of the mastering. I would avoid this prof if you can.

The class itself was not too difficult and I believe it is because of the professor. Labs started off well and ended with really tricky and time consuming work. Each lab did require some work and effort but my TA structured lab time in order to work on the lab and get help. I really respect how Professor Jiang quizzed the class. Tests were very fair and were straight to the point in order to see if the class understood the basic material (as every class should unless it is very relevant to your career choice). I lost track of time during my first midterm and bombed it, but it was fairly easy. I recommend STUDYING PROBLEMS IN THE BOOK.

Professor Jiang was such a sweet kind man! He really tried his best to teach us and was constantly asking if we had any questions. Anytime there was a question he would make sure to revisit that topic and explain it all again. Personally, I struggled to focus in this class, but I think that is because I was not interested in the content. As a result of this, I found myself getting lost in the flow of the lectures sometimes. I just recommend that you read the textbook for this class. Electricity, magnetism, and quantum mechanics are all vague topics that can be very hard to visualize and understand. The textbook does a great job making analogies and explaining things clearly though!
One complaint I have is that we were never given any practice exams. However, this issue wasn't that big of a deal because after the first midterm I realized that the exams are HEAVILY influenced by the mastering physics homework and the practice problems he goes over in class. When studying for exams, I recommend you redo the mastering physics and the problems in class! If you can understand all of those, you should be set to succeed in this class!

This professor was so mean. I dropped this class because the midterms did not offer partial credit and they were out of 4 questions, so if you missed 1 question you already had a 75%. He was incredibly rude to me and my friends during office hours, and despite the new stresses of an online quarter, he was unforgiving and insensitive. I've done well in all my other physics classes and actually enjoy the subject, but this professor made me miserable. I would avoid this professor at all costs!!!!

Jiang was pretty good for adjusting for the COVID situation. The class itself was not hard as the tests were on Mastering Physics where you had 3 tries to get each question right without deducting points. The homework was also on mastering and while it could be long it was okay. His lectures were decent, I just copied the notes ahead of time so I could understand him better, but I stopped going after a while. The labs were pathetically easy, especially if you do the simulations. There was a final presentation in lab which was easy but apparently I didn't do well in, because I got like 80 something percent in the lab component when I got 100 on all the labs which lowered my grade in this class. Overall, I would recommend taking it with Jiang because he really does care about your learning and is not too difficult.

He’s a very kind profesor. I took him during the COVID situation and he was really considerate about our needs and frustrations. He tries his best to explain what’s going on and answers questions and the end and sometimes during lecture. He seemed a bit confused on how technology works hahah, but I’m sure he’ll figure it out soon. Overall pretty straight forward class, he doesn’t try to screw you over which is nice.
