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.

Selling old lab reports for 30AL along with past exams and other course materials. All 7 Reports (Including Soil Project) + CPR are included and kept organized. Also selling 20L if needed.

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

Also, SELLING EXCELLENT LABS: 100% on almost all of them.

This guy has a hard grading scale on labs and calibrated peer review compared to the other professors. Soil project report takes forever due to all of the error analysis. unfortunately he will be the only one teaching 20l and 30al for a very long time based on past quarter records. Took 20l and30al with him. If anyone wants 20l labs and helpful bonuses, am selling. *************
