He is super picky with his lab reports and this class requires a lot of work for only being a 3 unit class. You have to go to class because the packets he hands out are the key to everything. You must get a super chill TA, the picky ones will kill your grade with how heavily the reports are weighted. Also, don't get an 8am lab. It was the worst thing ever.

After having a lot of other professors in the department, Pang definitely was the easiest to understand and had the best grading policy. If you ever have to choose between multiple instructors, Pang is definitely the way to go. Make sure you study the exam study-guides in-depth and look at past midterms. If you do that, you should be able easily ace the midterm. The final was multiple-choice and on a computer. Don't mess that up and study so you get 100%.

Professor Pang is definitely one of the best Chemistry professor I've had, and I didn't even take him for a normal Chemistry class. Even though he's very fast and has an accent, he speaks really clearly and explains really well. If anybody complains about his accent they clearly have not experienced other non-Native English speaker lecturers in UCLA. His study guides and powerpoint slides are really helpful. He pretty much nailed the foundation of Gen Chem for me. However, don't take them for granted because the final requires a strong understanding of the concepts covered (it's taken in the computer lab so just a heads up).

The labs we had to do for 20L are also not too bad. They may be exhausting because some take the full three hours, but they are not very hard conceptually. I don't remember having too much trouble doing the lab reports (the group report can be very tedious so pick good lab partners who will do the work). He is definitely one of the best lab professor for one of the easiest labs as a science major. If he's teaching any other required Chemistry class, I will immediately enroll in his class.

He was a pretty good lecturer and printed out his powerpoint slides which were pretty helpful. For 30AL the midterm was surprisingly difficult, but the average was pretty low and the test was normalized. Also, go to office hours, they're really helpful!

I don't know why Pang's reviews are so low! I thought he was a great professor. Very helpful in office hours (which he holds 5 times a week at varying times). Lectures are, for the most part, on topic. He gives out printed copies of his lectures, so you only have to fill in a few things here and there instead of writing down everything he says. This quarter, he passed everyone in the class, and ~30% of the class got A's and A-'s. The workload for this class has been reduced by a ton in the past few years, so I think it's totally manageable. He is also considerate of other classes (for example, when he knew the chem 20B midterm was coming up, he gave us an easy post-lab). His study guides for the midterm and final are SUPER helpful--know everything on those. And PAY ATTENTION TO SIGFIGS ON THE MIDTERM. Pretty sure everyone lost points on those. Overall, a great professor, and I would highly recommend him.

Wonderful professor: extremely clear in his lecture and helpful in office hour.

Pros: To the point in lecture...nice to talk to...hands out nice powerpoins.

Cons: Insane work load for a 3 credit class. I mean two written exams and a ton of lab writeups plus a 4 part writing assingment is ridiculous for this class. Handouts and instructions are impossible to read because they're half highlighted and random colors and all caps. Extremely easy to miss details and get marked down. Tests are easy conceptually, just nit picked to the nth degree by neurotic graders - if your answer is not word for word what the grading rubric says, sorry buddy, you're not getting the points. 50-60% of this class is busywork.

I think the only reason why I did well in this class was because I had a super chill TA who didn't really care about a lot of small details, but I really didn't like Pang as an instructor. He's not completely horrible, but the final was definitely not a very fair test. The midterm was a lot more bearable. If you can get almost all of the points on the lab reports and get ~80% on the midterm and final, you should be able to get an A in the class. His class averages are usually ~85%, and the class is uncurved since it is purely based on the amount of points you earn.
