A lot more work than BL, but definitely recommend taking CL with Pang. His tests are very fair, and he posts tons of practice problems. His tests also are not worth that much in his grading scale, so as long as you do the labs well, you will get an A.

Hard class

I've heard many negative things about Professor Pang and many negative things about Chem 14CL. Both claims were proven wrong as I took this class over the summer. Honestly taking it over the summer is much better than during the school year. Even though 4 labs a week sound daunting, there were MANY times when there were only 3 labs that week or the labs were short so we only stayed for half the time.
The material is connected with OChem 14C concepts that I thought were much more interesting than all the general chem concepts we learn in 14A/B/BL.
Now onto Professor Pang:
I have ONE negative thing to say about him and it's just he talks too fast. However, he is very nice in lecture and office hours and very encouraging. He even gave us 15 extra credit point assignments as well as free candy. His lecture slides are well organized with many important points clearly labeled, underlined, and printed for us before each lecture. During Office hours he answers any question and encourages students when they understand it. He uses very simple metaphors to explain concepts as well which were very helpful.
Labs: They were MUCH more interesting than 14BL's labs, Labs made up most of our grade and overall all the pre and post labs were easy. HUGE PLUS during the summer is some post labs are just 1-2 page worksheets that's it.
Exams: Oh boy, the exams. The midterm was completely fair. The reviews that said his study guide didn't help don't ring true (at least not for summer 2017). His midterm was all on concepts STRAIGHT from the lecture slides or study guide. There were no trick questions although one poorly worded question but overall I thought it was very fair. The final was definitely harder but again, it was a very very fair final. A lot of the concept based questions were heavily emphasized in lecture as well in the study guide. The titration problem had no trick to it. It was very straightforward. All in all, if you studied the study guide inside and out and read each slide carefully, there's no reason to do bad on the exams because it was so fair. (Textbook was pointless don't waste your time on the textbook).

I would recommend Pang for 14CL in the summer. It was very manageable and I had time to do other Extracurriculars. He was a very nice professor. Good luck bruins!

So I took this class for summer session A of 2014 and in my opinion, Professor Pang's class is more than fair.

Labs: Most of the labs were fairly easy with the exception of a few where the questions for the postlab were slightly difficult. However, I never went to office hours because I was lazy and still ended up getting around 95% on my prelab/postlab scores. A lot of the scoring also depends on how chill your ta is.

CPR: So during summer session, Pang only assigns one cpr assignment, which is seriously a lot better than two during the school year. By now, you should understand the horrors of doing a CPR assignment. Our topic was fairly easy and if you pay attention in lecture then you should be fine.

Exams: The midterm average was 66% and the final average was 68%. With that being said, I only studied a day before the midterm and about 3 days for the final and ended up scoring well above average for the midterm. The final however was extremely difficult, but keep in mind that everyone else had a hard time with it too.

Other: He also gave out two extra credit assignment which helped everyone's grade a lot.

Although I never went to office hours, I do feel that Professor Pang cares about his students. His lectures make sense as long as you pay attention and his lecture powerpoints are easy to follow. I do feel like he slightly curves the class just a little bit even though the syllabus claims that the class is a straight scale. I have always heard rumors that he had a strong accent or that his tests are unfair, but I heavily disagree with those statements. I really do recommend taking this class for those looking to fulfill the chem lab requirement over summer.

I took BL (2012) and CL (2013) during the summer sessions, which I've heard is easier because the TA's are told to grade more leniently given the compactness of the course. It fills up pretty quickly though so plan ahead. The workload during the summer is pretty intense since lab is 3 hours a day, 4 days a week with a prelab due almost every day. The postlabs are more spread out, since most labs take 2-3 days to complete anyway with some computer lab worksheets scattered throughout that should only take a few hours total. I was taking this with a humanities class and a part time job. I was doing homework/working almost constantly and thankfully it was only for 6 weeks. It was manageable but not recommended. One of my lab partners as taking CL with a physics class and she seemed pretty busy as well. I'd still rec this class for the summer, just take it as your only class.

For CL, I thought Pang did a decent job of covering the material. If you think he talks too fast, then record his lectures. My friends and I did that while sitting in the middle of CS 50 and it worked just fine. His midterm came a bit out of left field because one of his questions dealt with orbital hybridization/angles which was covered in 14C but not by Pang, he just expected you to know it anyway. His final I thought was pretty easy, but then again I always liked the 14C problems where you had to determine molecular structure from IR/C-NMR/H-NMR/Mass spec which was one of 6 questions on the final.

KNOW THE LABS. Like, when and why did you add this chemical to the solution? Why use a drying agent? Why can't you determine the melting point of this compound? If you used this TLC solvent, which organic compound would move the most/least and why? The computer worksheet labs weren't as relevant as the wet labs, so focus on what happened in the wet labs. He may not ask questions directly about the labs, but the basic concepts are a must know. I spent more times reading over the labs than I did the study guide. Do the study guide if you need help with concepts. If you already know how to calculate pH at various volumes and feel certain you can do it, you probably don't have to spend 5 hours doing the practice problems on titrations.

The CPR was kind of bull because we had to write in a letter format which was unnecessary, and it included a LOT of information that had to be described in a certain way otherwise points were easily lost, but since you're graded also on how well you can fairly grade others, the actual grade on the CPR isn't going to make or break you. I mean, the CPR is like 6% of your grade, if you at least put in some effort it isn't going to kill you. Pang actually decided to cancel the second PCR because we didn't have enough time for it.

My TA gave no fucks and was pretty chill. It seemed like as long as an attempt was made to do intro/procedure/msds you got full credit, it was only the study questions that were actually graded. The amino acid titration was kind of a bitch though because your accuracy was graded compared to the standard, which we had no way of knowing so figuring out where you went wrong/could have done better was impossible. Old labs were helpful for figuring out the format/what was and was not really needed for the intro/conclusions/abstracts, but like everyone else has said you need to understand the labs and not just blindly copy them. Know all of the important steps/reactions for the labs and why they were needed. If you just follow the procedures without really thinking about what you're doing, you're gonna have a bad time when the exams roll around. Our TA was incredibly helpful and would also try to assist us when something went wrong (we added something at the wrong time, forget to vent the damn separatory funnel, couldn't get something to dry, etc).

Our class average was an 85% overall, which is apparently the highest he's ever had. I don't know if he's making the class easier or just giving out more bonus points (has he done that in the past? I don't remember him doing that when I took BL...) so either he's not as difficult as he used to be OR he is trying to not get in trouble for failing too many people again. My friend went to office hours almost every day and she found them extremely helpful. Pang isn't a Saturday morning cartoon villain, he genuinely wants to help his students know the material. He doesn't want you to just memorize, he wants you to UNDERSTAND. Yes he can be a bit tricky, but he doesn't want to ruin your life. If you have to take a lab with him, don't automatically assume you can't do well.
