Overall, Dr. Pang was an effective professor; he gave clear lectures and printed out the slides for us so we could study them for exams. He provided study guides for both the midterm and the final, which I highly recommend doing before the exams. Lab reports were pretty straightforward, and if you needed help, the TAs and Dr. Pang host many office hours throughout the week. I would definitely recommend Pang for chem 20L or any other chemistry lab class!

20L is a very basic chem lab. Nothing in it is particularly hard, and the directions are extremely direct. Peng is a great guy; he's entertaining and sometimes funny, and he genuinely cares about his students.

Dr. Pang is the best! He makes it very clear on how you have to succeed and he's extremely approachable if you have any questions on your lab reports. He's also super nice and friendly. You do have to complete a pre-lab and a post-lab for every lab section and that's kind of obnoxious, but they're not the worst. You kind of adjust to them after a little while. I'd say each one takes about 1-2 hours on average although there are a couple that take a lot longer and a few that are shorter. Overall though, the class has a very clear set up and it's pretty easy to succeed. For my quarter, about 52% of the class received A's so I really recommend you take it from Dr. Pang!!

For the exams be sure to do the study guide beforehand--it helps. Office hours are helpful for labs too. He is very nice.

I loved this class. I personally messed up some labs but Dr. Pang was always perfectly clear on what he wanted. The tests were fair if you studied and reviewed the slides. The labs were straightforward and my TA was pretty lax as well which made things run more smoothly. Dr. Pang is engaging, genuinely concerned for student learning and just an amazing person all around. If you get the chance to take this class with Pang, do it!

Final grade: A

Class is really straightforward. Everything you need to do is given plainly in the slides and lectures. The labs are a big part of your grade, but they are graded by the TAs. Just be thorough while following all the guidelines. Ask TA or Pang if you have questions. The tests are big and scary with a bunch of parts, but are easily passed simply by knowing what was on the slides and lectures.

Professor Pang is a G. Despite having a bit of an accent, he is clear and concise in his lectures. He always comes to class prepared, gives out powerpoint packets; labs are pretty straightforward, as long as you follow the "cookbook." I swear, at times, Pang is so clear that it makes regular chemistry class concepts, such as acid/base, easier to understand. As far as the labs go, they are purely busywork, most of them are really similar to AP chemistry labs. The labs do take a while to do. Personally, I don't procrastinate, but if you are one of those people who likes to do everything last minute at 2 in the morning the day its due, from what I have heard, it can be done.

Some of the labs are partner labs, whilst others are individually based. Don't worry about bad data; Pang always says that he cares about the calculations and on HOW to do the lab, not the overall data results.

Pang is a ridiculously fair dude. I originally got a B in this class, went to talk to him about it and he changed it to an A-.

However, that being said, I got that grade because I had severely underestimated this class because of all these raving reviews saying how easy it is.

TBH, it THE LABS are pretty easy if you've taken AP Chemistry, however, his tests are the most excruciatingly annoying little shits ever. He has an EXTREMELY specific rubric for TA's to follow, dictating exactly how much credit and partial credit is to be awarded for each question. In it, he is looking for very particular things that he talks about in lectures, or asks about in prelabs. Master it the material, review conceptual bits on his slides, your post and prelabs, and most importantly, the study guide he gives you. Do it twice if need be. And on the tests, avoid mistakes, read carefully, think like Pang.

He's a very good lecturer and extremely helpful, if not a little bit too much by always rambling in office hours. He's also lowkey a troll, but not on grading. That shit he is very fair on it.

Labs depend on the TA. Mine was taking off points for having incorrect MSDS information (you'll know what that once you take the class). When you're looking for the safety diamonds, you'll find different ones for the same chemical. Look specifically for what form the chemical is, whether its powder, 5%, 10% etc.

Also another reccomendation is to finish up your prelabs and postlabs early to get them checked by your TA during his/her office hours. Other TA's can help, but they have different looseness to their grading if you will even though Pang is also extremely specific on lab rubrics.

Pang is a great professor. If you want to do well on his test go through the lectures notes and learn the definitions for the midterm. His tests are fair, just make sure you do the work in the class and you can get a good grade. Come to lecture and pick up slide notes.
