Super easy class. I didn't even go to lecture; I just came at the very end of class to pick up the lecture notes that Mr. Pang puts out at the front. Mr. Pang's lecture slides are pretty helpful but the biggest plus is that all the lab reports' guidelines are online with crystal clear instructions on how to get full score on them. The midterm only accounted for 11% of my grade so I wouldn't worry about it that much. I only got 81% on it and still aced the class.

Even though this lecture is in conjunction with Chem 20B (which I bombed and got a B- in from not studying at all), the material taught is not hard since it is not covered in depth. I did not learn anything from 20B which I took 3 quarters ago, and I still managed to do good enough on my final to net me an A after a day or two of studying.

Overall, this class was very enjoyable and you should take it with this professor if you want an easy time writing lab reports and taking exams. If you actually study in 20B, then you should have a much easier time than me in getting an A.

Johnny Pang is a very straight forward professor. He prints out all of his lecture PowerPoints and gives them to all his students which makes it very convenient to follow through. The midterm was fair however it was only out of 50 points so minor mistakes could cost you the A. They are very picky with significant figures I must say. However, the labs are the majority of your grade (about 60 percent), if you do well on those you're practically guaranteed the A. With that being said I am selling old lab reports for 20L.

Dr. Pang was a wonderful professor, he taught everything that we needed to know (though a background in AP chem is definitely useful). This class was not amazingly easy, but it definitely was not hard. Pang is a nice guy who cares about his students and works to help us succeed, I'm going to be taking him again for 30L in fall quarter because I

Take Pang. Really helpful and organized. Makes your life easier.

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.
