This class is definitely one of the best classes I've had here. Professor Pang makes everything clear in his lecture and is often funny. He is also generous in giving extra credit which compensates for the performance in the midterm. I would say this class is perfect if not for the lab session. You need to work triple hard to save your grade from a picky TA and lab partners who deduct your points by constantly forgetting to bring collaborative reports to the session.

Chem 20L is an easy class. Professor Pang was a nice professor and it seemed like he cared a lot about the class. The lecture gives you an introduction into what you're doing in lab that week and he prints out slides for the whole class to pick up. In the lab manual you'll read what to do beforehand and then go into lab and have no clue what to do but you'll figure it out with your partner. The midterm was really easy and I think the average was around 88%. The final was a lot harder but doing well on the labs should create a cushion. There isn't any curve in the class so how well you do on the tests and lab directly correlates to your grade.

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.
