Pang is NOT THAT BAD. Everyone needs to calm down. His exams are not as hard as people say they are, just make sure you know the lectures front and back and can replicate any of the experiments and the calculations required without a list of procedures. He says he doesn't curve, but I'm pretty sure he's lying, because a lot of people ended up doing well in his class.

I took Henary over the summer for 14CL, and for all that smack talk people give to Pang, I preferred him to Henary a lot.

I found this class really difficult, but it really wasn't entirely Pang's fault. He talks kind of fast, but his lectures are pretty clear and his accent is easy to understand. Make sure you keep his handouts and study them for his midterm/final. The labs aren't too hard, but sometimes you are put in group labs. My lab partner was a complete idiot and I ended up having to do everything myself while he doodled on a piece of paper in lala-land. Also, my TA wasn't very helpful because he made it clear he did not want to be teaching, and it showed. Hope for a good TA because that will help you understand the concepts behind labs. The midterm was difficult, but do-able. I found the final to be the hardest part of the class because of the fact it was an online test, which needed the same amount of work a typical chemistry final would have (as in, some questions needed a page of work). But you don't even get any partial credit for your work because it was entirely multiple choice and online. Doesn't make any sense to me, but it's how he does things. Be sure to understand the labs thoroughly, procedure and all. I ended up getting a B+ in the class, which was better than I expected. Pang says he doesn't curve throughout the course, but don't believe it, he definitely curves. All in all, it's a tough class but you can work through it.

Pang was a difficult professor. He had amazing lectures, I was awake and aware every lecture. The labs weren't so bad, they just took a lot of time and there's a lot of busy work. His tests are extremely difficult. They were really really deceptively difficult and he is very nitpicky when it comes to his grading. He did offer some grace with a final worth more if you do better on it but still, he's extremely difficult but somewhat unavoidable.

The class isn't extremely difficult, just time-consuming with two lab writeups a week. Pang wasn't as bad as I heard he was either. He talks a little fast in his lectures, but what he says is directly related to the weekly labs. The concepts are the same as you've learned from 14A and he expects you to either remember or review them. The hard thing about the class is the grading system. Don't take your labs lightly, make sure you know how to do the problems, and understand the concepts.

Listen to the post, posted before me!

You might hear rumors that Pang is a horrible teacher, but I personally think he teaches quite well. Yes, he does speak fast, but he knows exactly what he is talking about and his handouts are very helpful. Just make sure that you pay attention to what he says in class because what he talks about is exactly the material that he tests on. I received a 73% on his midterm when the average on the midterm was around a 63%, and I received a 62% on my final, but ended up with an A in the class. Pang says he doesn't curve at the beginning of the year, but it is pretty obvious that he does. I wouldn't mind having him again as a lab teacher.

Pang is a HORRIBLE TEACHER.
His midterms and finals are nothing like what he talks about or what is on his study guide, so that makes it pretty useless to go through his study guide in the first place.

He expects you to read your old 14A/14B textbook and be able to do a problem that he did not teach how to do in class. Granted you should be able to do it since you took 14A/B, it is still kind of unfair for him to expect to practice doing every single problems related to the class. You don't even really know what chapters to read in the darn textbook.

His lectures are also pretty useless in themselves. You end up trying to teach yourself the material by going to other resources such as wikipedia.

The labs are nothing but a waste of time. Pre-labs and Post-labs every week. Handwritten. In a carbon copy notebook. The TA's grading is all about the smallest errors (sig figs, an answer written down but seemingly not accounted for?)
If you want a perfect score on those reports, you pretty much have to check every single line or else you can be sure that the TA will just deduct points here and there for trivial reasons.

His exams are hard not in the sense that the concepts are hard but the way he presents it. There are a bunch of grammatical errors in his writing, and at least on the final, it seemed that he was trying more to test if you could read his test rather than actually test chemistry. There is barely enough time to finish, 65 mins for 27 questions, and it is on a COMPUTER. I don't really understand why he would want to make us take a final on a computer, other than the fact that he is too lazy to grade the exams himself.

Overall, a really bad teacher. Stay away from him if you want to keep your GPA up. Take the class at a local UC during the summer or pray that he won't be teaching one quarter.

WORST PROFESSOR EVER. he doesn't know how to teach and his only goal is to fail students.
been to his office hours a couple times and he is just a cold, mean, and uncaring person.
SHOULD NOT BE TEACHING

The worst professor I have ever had. He does not explain things. He presents them to you and essentially asks you to teach yourself. You DO need people's old labs simply for this reason. You must scrape together solutions to problems from what varied fragments people know and hope to do well in the class. He will put problems on his midterm/final review packets that have never been discussed in class, thereby nullifying the term "review". Professor Pang needs to re-structure this "course" and make it into a class intended for learning, not a fight for survival.

Professor Pang is a fine professor. It's the course that's extremely difficult and time consuming. Not curving the class makes it that much more difficult to get the grade you want in the class, but the class is only 3 units. I got an A in the class, but for me lab was nerveracking. 3 hours really isn't enough to set up your station and to run your experiment (especially when half of your materials keep disappearing from your drawer). But lab doesn't end there. You will be up all night doing lab reports that must be hand written on carbon paper. Try to get a lab section near the end of the week, because you will most likely put off the work until the night before, and the last thing you want is an 8AM lecture for lab the next day (equals all-nighter).

Pang is a fair professor. The truth is that Chemistry Lab will be one of the hardest classes you take in college. Take it seriously. PS: learn how to convert molarity to normality the CORRECT way or you WILL get it wrong and you WON'T get points back on your regrade.
