Quarter: Fall 2019

Easy class with way too much work. Pre-labs and post-labs are very time consuming and it makes me very sad. The midterm and final are high variance. Though the problems are relatively easy, misunderstanding one concept and cost you a lot of points. I misunderstood one concept and that cost me 10 points on the midterm. However, that is entirely my fault and if you pay attention and do the labs, you will be fine.

Though in the schedule it says the lab is 3 hours, realistically it is more like 1.5-2 hours

Overall, chem 14BL is very doable. Pang offers a lot of office hours for you to go to, although I have not ever been to one. The labs do not generally take the entire time, and the post lab reports are not that difficult. The midterm and the final are also not the super difficult side, and are very fair. I would recommend taking this class!

While 14bl is a review of 14a and b with application to lab experiments, I still found Pang's exams pretty challenging. He would sometimes ask us about obscure concepts from lectures or labs. Be sure to go over lecture material, understand lab concepts, and do his review guides.

(Pre-) Lab reports take a lot of time at first but get easier over time. It doesn't really matter how well you do the experiment. And as long as you do the study questions correctly it's easy to get all the points for the lab section of the grade.

He offers daily office hours, which is pretty great (but I never went to them :0)

Quarter: Spring 2019

June 11, 2019

This class honestly sucks. Professor Pang is super hand wavy during lecture, telling you to look at different things but he doesn't really explain much. The class is a lot of work with all the lab work due. Pang's instructions are super dense which makes it hard to read everything he posts for labs. Tests sucked, mostly because you lose points for the most ridiculous reasons. You could pretty much lose points for the most stupid reasons in every assignment for this class. Lecture is once a week for 50min, but his tests cover stuff way beyond the scope of what we learn in class, so it's up to you to do a lot of extra work to try and be prepared for tests. I guess the logic is that it's a review of 14A/B, but for someone who hasn't taken those classes in a while it sucks. Be prepared for one of the worst classes you could take at UCLA.

This homie felled at least 1000 acres of the Amazon this quarter alone. He prints out all of his lectures slides and put them in these massive piles at the front of the lecture hall. If you f with that, then this is the guy for you.
Fair warning, some of his instructions / guidelines are p wack, try and get a good TA because you most likely will have questions.
Don't underestimate the midterm either, the material is all rehashing from 14A and 14B, but it has a p low point count, so little mistakes can cost you big time. Otherwise, Pang's a cool dude.

This is the worst class I have ever taken at UCLA. It is only worth 3 units, but seemed like the workload of a 5 unit class. The lectures only cover basics of the class, while the labs and exams expect you to know the material much more in depth. There is a midterm and a final, both are extremely hard. No equation sheet is given. I have spent many nights crying about this class. Many of the concepts in the lab are the same as the concepts taught in Chem 14B, but Pang uses different methods for solving and it is confusingly different from the methods taught in 14B. There is a pre and post lab assignment due every week that will take 2-3 hours to complete each. The final is worth a third of your grade and is impossible. You pretty much can't avoid this class if you are a South Campus major at UCLA, but it sucks.
