Dr. Pang is by far one of the best professors I've had the pleasure of taking in my 4 quarters at UCLA. I took 20L with him as well, and that experience was similarly a very pleasant one. Dr. Pang holds office hours every day to help any student with questions about the pre-lab, experiment in general, or class in general. Dr. Pang is very clear and engaging in lecture. He repeats everything he says like 5 times per slide so that helps. Pre Labs are a b**** but if you manage your time, are doable. Start over the weekend if you can. Taking this class without having taken Chem 30B is really doable. Kind of difficult but Dr. Pang teaches the class knowing that some students haven't taken 30B. Though the concepts in this class are more complex than in 20L, this Lab class has by far been my most favorite. The experiments were really fun, in that, you learn to synthesize, analyze, and identify really cool products. The midterm and final exam were pretty difficult. The final project, soil lab, was a pain in the ass. Fun times though, nonetheless. Dr. Pang needs to teach ALL Lab Classes at UCLA! (for the 30 series)

If anyone needs the regular labs and soil lab for this class, email me at *************. I got As on all of them.

After having a lot of other professors in the department, Pang definitely was the easiest to understand and had the best grading policy. If you ever have to choose between multiple instructors, Pang is definitely the way to go. Note that 30AL requires a lot more effort than 20L with labs held twice a week and many hours spent compiling the pre-labs/post-labs. Make sure you study the exam study-guides in-depth and look at past midterms. You'll be a lot better prepared for the midterm/final if you follow through with reviewing past materials and the Study Guide. It's also always a good idea to review the lectures slides as those are critical for doing well on the exams. If you do all the above, then the exams are fairly reasonable.

Pang is probably the best lab professor you will get for 20L and 30AL. He is very concerned about student learning and often gives extra credit if the class does well enough on the midterms. His class is always interesting thanks to his engaging lectures.

That said, if you hated 20L like I did then you will absolutely despise 30AL. Two labs a week and a group project/presentation at the end of the quarter. The labs themselves aren't difficult they're just time consuming. The soil project, however, is probably the most stressed I have been my entire college career so far. The project is doable within 1 day if your group really knows what it's doing but it's still a pain. You have to present your findings and then write up a lab report for it.

The midterm and final are actually not that hard if you go over all the concepts of the class and do the study guide questions.

class: 30al and 20l
TA's tick off points like crazy due to tight grading standards for both 20l and 30al. also, 30al is 2 labs/week for a total of 6hr/wk. And you will have on average, a prelab and a postlab for each lab meeting, which means double the 20l work. Finally the soil project, which is in groups of 4, is painful. You get 80grams of a mix of mostly sand, 2 organic compounds, and 2 ionic compounds. You have 4 lab meetings to figure your own procedure to identify and quantify the compounds based on what you learned (not really since most groups have crappy procedures that pang will outright criticize when you present). And you will lose points if you dont get within %80 of the true quantities (only the ta knows the true values so you cant really falsify the data). And if you end up using beers law for inorganics, prepare for hours upon hours of data analysis. Still, enjoy the decent equipment since 30bl equipment is a downgrade. Finally, you need to think like an accountant, keep very careful track of multiple due dates and dont show up late; many people go down half a letter grade for forgetting stuff or showing up late. And if anyone wants old labs and notes for 20l and 30al, am selling complete,graded, high end sets *************

I had him from 20L as well, and for 30AL, he's hte same as before: fair and concerned about student learning.

However, labs take a long time and the work is about 2X that of 20L.

Also, Pang's midterm and final were overall fair but the final was very long (took everyone the whole three hours)

Record his lectures and focus on the lecture slides.

Mohrig textbook is helpful but not mandatory to read every little snippet like he sometimes empahsizes.

Overall, I recommend him but be prepared to work a lot
