He tends to repeat himself over and over again, sometimes it's good but sometimes it got quite annoying.

Lecture material isn't that hard, just basic gen chem stuff.

Midterm: make sure you do practice problems he posts. Our average was 59% and it's straight scale, i believe only about 10 students or so got an A.....

Final: He asked some ridiculous question like "wt does NFPA stand for?" & "For log, wt is the decimal of the number to the right of the decimal point called"....other than that it was pretty straightforward...but in one of the questions he intentionally tricked us.. so make sure you read the question VERY carefully

Make sure you get old lab reports from someone somehow...

I got an A and partly because I did well on midterm and i got old reports..... make sure you study ALL the material in the lecture notes, and practice calculations (which isn't that much compared to most other classes)

Pang taught me more chemistry than my chem professor for 20B. Yes he does go a little fast but he goes over material very efficiently. I thought I was going to fail because I bombed the midterm, BUT I managed to get a B+ because the final was super easy!! Seriously, the class is pretty straightforward and you can't blame the crappy labs on the professor because they use the same labs every year.

Overall, Pang is a good lecturer and professor. Reasonable and to the point. I mean, give the guy some credit. He has only an hour of lecture a week to cover all the material for the class, and I doubt that other professors would teach Chem 20L any better. Also, he's almost always available, as I constantly bombarded him with (what probably seemed to him as stupid and obvious) questions haha, but going to office hours really helped solidify my comprehension of the labs--which is SOO crucial. Especially if you didn't copy lab reports. To tell you the truth, the number of students who actually copied from old lab reports is probably overrated, as most students from my lab discussion didn't copy. Even if you do, it won't help you much in the long run on the exams. The best way to do well in the class is to write up your own lab reports and go to office hours. Also, pray that you have a nice TA because, I had a pretty nitpicky TA that would take off a lot of points on labs--which made the whole class experience pretty miserable as I constantly worried about my grade. I did very well on the midterm, and bombed the final. But in the end I got an A, I guess Pang lowered the scaling for the final... because DUDE the final was difficult.
