Pang gives out his slides during lecture and these are REALLY useful. However, the packets have blanks in them that you have to fill in yourself when you go to lecture. So make sure you show up on time, get a packet, and fill in all the blanks because you'll need the packets for the labs and tests.

Your experience in any lab class is largely dependent on your TA. I had a bitchy TA who was super picky about everything and graded harshly. My friend had a chill TA who was really nice and graded easily. But in the end, Pang normalizes all the grades so it really depends on how well you do compared to others in your lab section.

The easiest way to do well in a lab class is to use older labs as reference. Get some, and you'll be fine.

Before actually starting 20L, I heard horrible things about this class, partly based on the more negative reviews on Pang.

Nevertheless, I must say that I do not regret taking Chemistry 20L with Pang. Yes, the labs take a long time (especially the Chemical Kinetics and Beer's Law ones) but Pang is a straightforward lecturer who, despite his accent (which is not that bad) does make sense when he tries to relay chemistry concepts to the class. In my opinion, he was the best professor I had last quarter, and I was bummed when he didn't receive a round of applause when the final class was finished.

Tips for the class:
1. RECORD Pang's lectures. I listened to most of his podcasts before his exams and that really helped me.
2. Know Beer's Law. If it pops on his midterm, it will be on the final again most likely, and if it's somehow not on his midterm, it will definitely be on the final.
3. For his exams, this is his format: Pang gives you a convoluted situation with a lot of jargon that may scare you at first, but look for the main idea and what the question is asking for, and you will be fine.
4. Do his study guides. Although his exams focus more on applications, knowing the study guide concepts help you understand the basics better.
5. Get previous labs. They help immensely.
6. Make sure you have a good TA that is also a nice person; my TA really got on my nerves so just watch out.
7. Go over Pang's lecture notes; Doing this concurrently with listening to his recorded lectures will help.
8. Go to Pang's office hours! He is quite helpful and nice. Every time I asked him a question, he gave a response that answered my questions well. His concern for his students is satisfactory. Also, Pang never came across as rude or arrogant, which is a plus.

Good luck to you all. Pang gets a bad reputation, but he is a good professor who does care about his students.

Honestly, I thought Professor Pang was a pretty good lecturer. He was straightforward, and I learned more in 20L than I did in 20B (although I had a pretty bad professor in 20B and I did take 20L after 20B).

The grading scheme was: 18% prelabs, 35% postlabs, 7% "lab technique" (which I can only assume was a freebie depending on your TA), 8% CPRS (theres 2 of them), 10% midterm and 22% final. Therefore, your TA determines about 60% of your grade, so it helps having a nice one who won't take off too much for sig figs or miscalculations. (Side note, I had Dimitri Bikos and I definitely recommend switching to him if you can)

Your CPRS are writing assignments on certain topics graded by people in your class, so if someone decides to be a bitch and mark you off for something, yes that can lower your grade, but its weighted against 2 other peoples' assessment of your CPR, and your own assessment of it based on the program's grading scale. Basically, the closer the average of the 3 scores are to the score you gave yourself, the better your grade will be.

The midterm and final were pretty hard. His study guides are kind of useless, its just questions of every topic he covers. It's definitely not a guideline to the types of questions he puts on the tests. You might as well do them though, considering there's no other way to study for his tests.

For the final, study your post-labs. At least for my class, he put alot of "freebies" in a sense that had to do with stuff we learned from the labs themselves, so actually study your labs, not just the process but everything about it.

Overall, it's a hard class, and you will put a lot of time into it. The post-labs and pre-labs are very tedious. You can't get around not having Pang for 20L, since Pang teaching a lab is more regular than a lunar cycle. However, you can control the TA you get, somewhat. Do whatever it takes to get into a good TA, because that's more than half of your grade. You can even try making up some excuse that you have schedule conflicts unless you go to a certain lab at a certain time. Also, it helps to take the class with someone you know, so the labs will run smoother and you can work on the post-labs at your own discretion.

Before I say anything, PLEASE DON'T MISS THE MIDTERM. This is an 8am class so if you are one of those people that always oversleep....be careful. As stated in the syllabus, you will not be able to make it up for any reason besides serious illness with doctor's note. The midterm is only 10% of your grade, but he has a rule where you have to get 50% in each category to pass the class. In the testing category, the midterm accounts for roughly 31% and the final, 69%. So if you miss the midterm, you must score at least 73% on the final to pass the class. Let me warn you beforehand though, his finals are HARD.

The grades you get on your labs depend solely on your TA. In a sense, the professor doesn't affect your grade much since midterm and final combined are only 32% of your grade. So I wish ya'll good luck on getting an easygoing TA! Get old labs from people if possible; they help A LOT. Lectures are not as important, but make sure you have someone get you notes. Study guides help you get the general concepts, but move on after understanding them and don't spend much time working out the problems. Review your calculations on your lab write ups instead to apply those concepts.

I would recommend taking him because he really cares about you being able to learn the materials. Go to OH if there is anything you don't understand and you will most likely get the help you need.

20L is a hard class, let's get this straight. In order to get good grade, you need to put a lot of work into this class, so expect about 5-6 hours a week to work on the post/pre-labs, and extra 2-3 hours for the writing assignments. Pang also said he wouldn't curve the class, but he gave this extremely hard final that he ended up curving it anyways in the end I believe.
The final had nothing similar to what he gave in the practice one so really, good luck on it. My advice is to go over the slides and understand every single word written on them.
Postlabs and pre-labs, even though they may not be that hard, take some work to understand them thoroughly, which is one thing you should do to prep for the final.
I did all those things and ended up with an A for the class.
Good luck to you all!
