Pang is seriously not that bad. He is a really nice guy. I was late to my lab and I was really scared but somehow I got to make up the lab. (but all in all you should not be late to your lab, it REALLY screws your grade up, listen up for people in 8AM class). His class is composed of PreLab, post lab, ONE midterm, 2 online writing assignment that counts for 20% total and I think technique in the class? or something like that. Don't forget to TURN IN your writing assignment to TURNITIN. Even tho the old lab helps you figuring out what to do quickly but I wouldn't recommend just copy mindlessly because ultimately, it will cost you the final/midterm grade. Those two tests are fairly difficult only because he asks both the calculation and you really need to know the lab that you do. For example, the stupid pipet video at the start of the class was asked in the final and it got me mad because i lost the easy point. But try to make an outline of the PURPOSE and the TECHNIQUE that you use and WHY YOU USE THEM. trust me, it was on my final and I don't think why he wouldn't give the same to you. But I learnt a lot about being a scientist in his class and how to calculate errors especially: inherent error, RAD, RSD those are pretty fun to do. Pang is not unreasonable, you just need to spend time and effort in this class. Oh, right, PAY ATTENTION to your lab because sometimes the TA is really picky and ALWAYS find something to take points off (and the prelab is mostly 10-15 pts) so it really screws your grade. A is achievable in his class if you spend the appropriate amount and effort.

Tip: Take a tape/digital recorder to class.
Helps A LOT.

Great prof. Has nice taste in pants.

I have to admit... I think Pang is really good looking, and he is always dressed very well, so maybe that will skew my review a little bit.

His class isn't that hard, but it takes a lot of dedication. Set aside time to make sure you jump through every hoop he throws at you, including the online assignments and all of the pre/postlabs. I spent time on all of them and got about a 95% average on them. Most of the points I lost were on significant figures-- the TAs can be really picky about small things, so watch out. His tests were fair, and you should be ok if you can convert units really well. The concepts aren't even hard, but there are a ton of unit conversions and calculations to get through.

Bottom line: don't be afraid of him, and don't listen to the horror stories. He wants to reward you for your hard work, so show him what you've got.

Ok, I'm gonna write straight up to avoid this guy. His lectures were clear to me, but that's about the only good thing. There is SOOOO much work for a 3 credit course. The amount of work we had was more than my other core classes. The labs are just time consuming, other students grade your essays which kills your grade, and the exams are NOTHING like what you study for. What really matters is that students should understand the concepts. I think I understand chemistry well judging by my chem 20A and chem 20B grades, but his class was just nonsense.

I had Pang for chem lab. The TA does the grading of all the labs, but Pang does the tests. The tests are easy and straight forward; i don't know why everyone complains. If you can convert quantities and know sig figs, the tests are a sinch. However, he grades very hard and doesn't curve. He is a really nice guy though (ironically from how he seems in lecture) if you happen to go to office hours.

I'm not really sure why everyone's bashing on Pang, but he wasn't intimidating. In fact, he would also strike up a chat and offer you a seat when you go to his office hours. He'll also answer any email you send him, even though it was 9 pm on a freakin' Sunday when I got a reply from him.

Anyways, he does speak very quickly, but he has to because he has a limited time to cover all the material that you'll need to know in lab. The handouts were useful as long as you filled in the blank spaces and then organized them later on. Hey, I prefer him over Skibo since Skibo never covers all the material in lecture.

As for the lab reports, spam your TAs and Pang; they'll reply. Make sure you really know the study guide like the back of your hand. Also, studying for 20B is like studying for 20L, and vice versa. Know your concepts, know the calculations. The midterms may be a bit of a time crunch, but they're not too bad. I got an A in the end.

He'll visit all of your lab sections, so if you had something to ponder, ask him when he shows up. He also gave us extra credit for completing a survey, so isn't that great? Plus, you gotta admit he dresses up pretty nice compared to the other professors.

First thing to note... he talks REALLY REALLY REALLY fast. Grading wise it's no curve so feel free to help your friends. :) Labs are tedious but aren't too bad, lab write ups are long but again not terrible, but the thing that gets you, is the midterm and final. He is very nit-picky about measurements and calculations so be weary of that. Overall a good professor because he talks about what you need to know and doesn't try to trick you about what's on the midterm or final. Go to office hours if you can because he is very helpful! Very hard, but if you put in the effort, it should be okay.

Everyone warned me not to take Pang but I did anyways, and I don't regret it. Maybe it's because of his probations, but Pang was a solid professor. His lectures were good, he passed out handouts so you didn't have to write down that much. Also, most of the stuff is covered in 20B with the exception of Beer's Law so if you know 20B you know 20L. Pang talks really fast which is kind of amusing but still really understandable. His exams are moderately difficult but really if you did the labs you can get good scores. Also Pang was very accommodating to me when I got into a bike accident and nearly busted my hand. Maybe he was not concerned before, but right now he is quite concerned with his students and I would recommend him for anyone.

Pang speaks quickly, but explains concepts pretty well. Make sure you not only understand how to do problems, but the concepts behind them. His accent is not bad at all (why are people complaining about it?). I did well on the lab reports (90%+) and I did slightly above average on the midterm (around 75% when the average was in the high 60s). He said at the beginning that he doesn't curve the class, but this is impossible. I got only around 50% on the final exam (which was proctored in the computer lab and was very difficult) but I got an A in the class... So obviously he ends up curving the overall grades. Simply put, if you can get someone's old lab reports, do it. This saved me a little time but mostly helped me learn the concepts more quickly instead of getting bogged down in the details.
Put the time into this class and you will do fine. I never heard any horror stories from people who actually made a good effort. Also, go to office hours if you're confused. (I didn't, but my friends did and he is very helpful, polite, and caring!!) Expect the worst on the exams (...most science exams at UCLA are as difficult as Pang's!) and study hard, and you should be happy with your grade at the end.
