I really liked this class. The labs that we did were pretty simple and I genuinely enjoyed some of them. The midterm and the final were both extremely fair and were based off the lectures slides (which were posted) we had in preparation of the labs. It felt like an easier and more fun version of gen chem 2. However, it is important to note that the prelabs and the postlabs can be a little unforgiving so I would double check some of the work, especially when it comes to sig figs and units.

I would highly recommend taking this class with Dr. Pang! He is extremely clear in his lectures, and you can tell he's passionate about making sure every student can succeed. He's often funny, and his lectures are very well paced throughout the 50 minute allotment of time. The only real work you have to do is a pre-lab and post-lab for the experiment every week. These were definitely manageable, but there were a few weeks early in the quarter where these assignments took a lot of time and effort, but it eased up after that. The experiments themselves were thoughtful and beneficial to have a physical understanding of common topics that are covered in Chem 14/20. This was a great class and I would undoubtedly take it again!

I decided for my reviews now I will justify my numbers for the review:

Number Score:
Easiness: 5 - The class is pretty easy, content wise its not hard to understand. The labs are interesting and if you put in at least some amount of effort to actually learn the content and learn for the sake of learning you should get an A.

Clarity: 5 - Very clear professor, gives very clear instructions and very clear during lectures. He wants you to understand the concepts behind the lab and its connection to your specific field. He does talk pretty fast and does not record lectures so be ready for that.

Workload: 3 - Post Lab and Prelab work is alot of busy work so expect that pretty much every week.

Helpfulness: 5 - Super helpful during office hours and really good at explaining concepts during office hours.

Overall: 5 - Professor Pang was great probably my favorite professor I've had at UCLA.

More Extensive Review:
Professor:
Professor Pang is one of the greatest professors I've had at UCLA and my personal favorite one I've had so far. He is super helpful and sometimes funny. He really cares about the students and wants them to learn. He wants them to understand the actual concepts in the lab and their real world significance. One of my favorite things that professor pang did is he would come by during your lab sections and check on the students. He would give compliments if a student did a good titration or a good separation etc. I could not speak more highly of Professor Pang.

Class:
Personally I really love chemistry so I loved this class, I enjoyed my labs. There was alot of busy work for the pre and postlabs but nothing you can't handle. I really liked my TA and he was super helpful so that contributed to my positive experience of the class. For the midterms and finals be careful because alot of people sleep on it and finish with a B. To study for it I recommend doing the Practice Problem Sets (PPS). I believe if I remember correctly an A is up to 90% rather than 93%. So it shouldn't be too bad. Good class overall.

Professor Pang is an incredibly kind, caring, and understanding professor. His lectures and overall class are clear, concise, and organized. He cares about student learning which is evident through his office hours as he explains concepts thoroughly and slowly, regardless of their simplicity. I do wish he posted recordings as he did in previous years, but that is a minor caveat.

Dr Pang was very organised, consistent and reasonable with his expectations. He made the content applicable and interesting, and focused on delivering the material efficiently. I would take another one of his classes if I had the chance.

Pang was a great professor; he explained things in a way that was clear and concise. He taught chemistry better than I have ever been taught before. I took 20B last year, but I wish I had taken 20B and 20L concurrently since Pang provides such good insight on the material.

I found Dr. Pang to be a really engaging lecturer and he was generally very clear about everything. I liked how he even came to the labs sometimes, it felt like he really was involved with his students' learning. I think it would be nice if the slides that were posted were already annotated from the beginning, since that would be easier for studying ahead of time, but that's just a minor complaint. Also, if lectures were recorded, that would be nice too, so that we can go back to them.

I enjoyed this class a lot, and Pang is nice, clear, and understanding. The midterm quiz was an online and open note, so I didn't find that too difficult. The labs themselves were interesting, but the pre-labs and post-labs did take time to do, so I would make sure that you don't wait till the last minute to do them. Your TA also does matter since they grade your pre-labs and post-labs (shoutout to Emily!), and I asked my TA a lot of questions just to confirm that I was doing the right thing so make sure that you get along with your TA well.

I flopped badly on the final though, which is why I ended up with a B+. It's something that you need to study for, but it isn't hard in terms of content. I do think that if I studied better I would've been able to get an A/A-, as I had an A before the final. Lectures are also optional since he records them and doesn't take attendance, and I'd recommend just watching them on 2x so you make sure that you understand everything. However, you don't need to watch them if you can simply understand the slides; I just like being thorough with the content (clearly didn't work though for the final lol).

johnny made me feel like i could cure cancer or sumn. a beautiful spirit and an incredible soul, you will do well in this class if you care a bit insyaallah

Agreed with most of the things other people have said about Pang. He is very concise, and should be the golden standard for professors here at UCLA. Lectures are easy to follow and Pang provides details to the T for labs and assignments, for the most part. The only thing that was missing from this class was grading details. The most that you get back are the assignments graded by your TA, the single midterm in the middle of the quarter, and a confusing grading system for the writing assignment. I wish Pang would use Canvas to setup a grading system like other professors but with labs I understand it can be difficult. I was on track to get an A this quarter but had a bad day and performed well below average on the final, so that sucked.

Assignments are very straightforward and each question is detailed in terms of what you need to do to solve. Pang uploads lecture slides and recordings making it easy for those who miss a lecture. I had a lot of anxiety approaching this quarter about this class because I was horrible in high school labs, but most of the labs are actually well under the 3-hour timeslot and from what I've seen Pang is great at picking chill and respectful TA's.

To do well in this class, I recommend following the practice problem sets. Pang attaches answers (unlike Barr lol) with real explanations so you can struggle but then understand what exactly happens. They're also pretty easy to study from in my opinion. Start the prelab and post-lab assignments as soon as you can. Especially in the second half of the quarter, try to start them right after your lab is finished because they often draw on information from the lab i.e. the normality of a certain solution or any observations that weren't asked of you to make in the lab itself. Sometimes these assignments took me a few hours so take that as you will; you will get exhausted trying to do it the night before, so give yourself some room to breathe. They aren't hard, just a bit time consuming making sure you get everything right. Also, some assignments are group-oriented. Other than grading and the heavy materials fee (I think I ended up paying about $130, something like that), this class is great.
