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.

I had heard a lot of bad things about Pang before I took this class, but I have no idea what everyone was going on about. Pang is an extremely thorough lecturer. Since this is an 8 am, not a lot of people want to come to class. To encourage students to show up, he prints out lecture guides for class for you to follow along and fill in the blanks. While it's true he doesn't curve tests, it's because it is very easy to get a good grade in every other aspect of the class. So suck it up and study.

People also told me that you can only do well in the lab portion of the class if you have someone else's notes, but that's not really true. You can do fine if you understand the goal of the labs and read the in class notes. Comparing answers with your lab partners is also a good idea. The final is pretty easy if you review everything and understand the concepts and how to do some basic calculations used in lab. It is multiple choice and on a computer. Some people didn't like it because there was a timer in the corner.

Overall, I enjoyed this class. Pang is an effective teacher.

I was scared to take him because of all these bad stuff I heard about him but I actually think he was not bad. He does talk fast but it's not to the point you won't understand him. You should know a lot of the stuff anyway because a lot of the stuff he goes over is from 14A and 14B. As for the labs, just get a hold of those old lab reports from previous students because they'll save your butt and time. But don't rely on them too much because you'll need to actually know the material to do well on the midterm and final. His midterm was easy if you did his study guide. His final was reasonable as well. I actually enjoyed labs too!

Pang is the bane of my existence. Really, really obviously doesn't care about student learning. He's been on probation TWICE for failing too many students! If you can avoid him, avoid him.

Effectiveness: Pang isn't a very good lecturer. He tends to repeat the same statement(s) over and over and over, and after awhile it gets a little irritating. He comes off as a mean, but regardless he is very fair in grading.
Difficulty: I would agree with most that his class is a little too much work for a 3-unit class, but there's not that much he can do to cut down the work load.
Concern/Availability: Pang doesn't show that much concern for his students, but in any case its better to seek help from your lab TA and get to know them, since they are the ones that grade your labs (the bulk of your grade).
Overall: Professor Pang isn't that great, but you could certainly do worse. The professor aside, I would take 14BL AS SOON AS POSSIBLE after 14B, since the majority of the class covers acids/bases and kinetics (14B topics).

Simply put, Pang flat-out sucks. The man has a penchant for confusing his students and ultimately not giving a damn about their learning of the material. I've never been to a lecture where literally NO ONE is communicating except the professor himself. The ONLY voice I have ever heard in lecture is Pang's--and his freaky super-speed rambling. This clearly goes to show that everyone is so put off by him that people don't even bother asking questions. It's quite odd, actually--considering that this is a fast-pace chemistry class where the material can often be difficult to grasp.
And when it comes to his exams, the frustration only intensifies. Sometimes, the most obscure definitions are asked, and it surely doesn't help that the graders are extremely nit-picky about everything. Pang will give you a study guide and all, but trust me, you can study that thing all you want and it won't help too much. I don't even know why he passes out those things, much less calling them "review" sheets. The only positive is that the labs are somewhat fun and interesting. Lectures, however, will probably put you to sleep faster than a sleeping pill combined with CSPAN.

Professor Pang is a very good lecturer. Many people think he speaks really fast, but it helps you to keep awake. Don't miss any lectures because they will help in both labs and exams. The CPR are stressful at first, but you just have to get a hang of it from the first one and you will do well on the second CPR. His grading scale is fair because it helps to normalize the lab report grades if you have a hard TA. If you go to his office hours, he is very nice and is always willing to explain anything. His exams are not difficult if you go to his lectures and do his review sheet thoroughly. He definitely tests how much you understand the materials and not how much you can memorize. He really isn't as bad as people think. He might be intimidating in class but if you just talk to him, he is a nice professor.
