Professor Pang is an awesome instructor. He really makes you understand chemistry and labs on a conceptual level rather than just mindlessly plugging away at equations and not making sense of them. He is extremely kind and patient! If you don't understand a concept and attend his office hours, he will make sure that you will really understand it. I highly recommend taking Professor Pang

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 *************

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!

P/S: I'm selling all the postlabs/prelabs, course reader as well as all the notes I took in the class( good review for midterms and finals ). Contact me via *************
