This is my first ever bruinwalk review but I felt like I had to write one because the reviews on here doesn’t do Pang justice. He’s a very effective professor and gives little hints to help you memorize stuff while also being funny. Also he prints out the slides for the lectures which makes it easier to follow and take notes since you don’t have to worry about missing important info since most of it is already there (rip the trees tho lol). Pang also gives you a study guide for the midterm and final with solutions like what an angel. The study guide is harder than actual exams so you’ll do well if you just study off of it. The labs are time consuming but the manual gives you step to step directions. Some of the reviews blamed Pang for the structure of the class but it’s a freaking lab of course it’s going to have a heavy workload and every 14bl professor is required to assign those labs. Overall Pang is a real homie and I wish he taught the regular chem classes because I would’ve gotten way better grades with him as the professor

Professor Pang made this course very accomodating for students everywhere. Asynchronous lectures, light workload, and 24 hour exams. The exams, as well as the homeworks and lab reports were light in terms of courseload. I would spend about 4 hours a week max working on homework and lab reports. His slides are concise and informative, and we breeze through a lot of content in such a short time. His lectures are done on PowerPoint though, so no 2x speed. He is available for many office hours, and labs were not very time consuming (we could leave early). He is also very responsive to emails, so don't be afraid to reach out if you need help.

Overall, Professor Pang has been one of my favorite instructors so far, and he has made this class very fun! I would take this class again with him in a heartbeat.

The lecture was pretty boring, almost all the material is a repeat of 14A and 14B. Pang as a professor was pretty awesome though. Nice, personable guy who would occasionally throw out jokes in lecture, but would come back to the point quickly. He prints out copies of his slides for everyone to write on during lecture, which is awesome. I really got the vibe that he cared about his students. During office hours he was pretty chill. Labs were fun if you like hands on stuff. Overall, ok class, good professor.

This class is amazing! Take this with 20B(H) as it really does go in parallel with many of the topics learned in class. AP Chemistry helps a lot with the topics, but it is by NO means needed at all. Pang's asynchronous lectures are extremely helpful, and are in PowerPoint format rather than a video. It's super intuitive to watch the slides and listen along, rather than trying to rewind a video.
-
The lab section with the TA is super chill as well. It never lasts longer than like 30 minutes, and after that, its an optional worksheet to complete. You can just use it as supplemental office hours or review, and you never have to stay past the initial TA lecture, which is graded for participation (usually a single clicker question via Zoom poll).
-
Homework is light compared to a normal class, but the class is only 3 units. There's typically one lab assignment and one homework assignment each week, and they are all very manageable. Some of the later labs get a bit longer, but they are never difficult, and the majority of the time is formatting tables in Excel. Speaking of Excel, some technological knowledge is helpful, but the tutorials provided on how to use Excel mean that even with no prior knowledge of spreadsheet programs, you will be absolutely fine. Just check your work with some people from the class, and you really can't go wrong in this class. There's also one random writing assignment during the quarter that you can think of as a homework assignment with less calculation and more writing. It's easy and you can get some free extra credit if you do well on it.
-
As for midterms and finals, they're called "quizzes," but its a just a really long comprehensive homework assignment. Again, nothing tricky at all, just a bit lengthy, but you get 24 hours for a 3 hour assignment. It's very doable in even just 3 hours (Math department has something to learn from this class), and you're allowed to review lecture slides and homework during the tests. There are no unfair questions and everything is made very easy and accommodating.
-
Since the majority of the class is asynchronous or via TA discussions, you don't actually see Pang all that often. Do yourself a favor and go to office hours, this man is so caring and accommodating. His lectures are super straightforward and to the point for people who just want to get through the material fast, but he will take the time to elaborate and help out if you ask him to. It's really the best of both worlds.
-
You're probably going to need to take this class anyway if you're looking at CHEM 20L reviews. Just do it with Pang and look forward to it. As long as you don't put all the work to the last day, this will be a very stress-free class.

Pang is the best. I really enjoyed this class, mainly because the professor is so caring and helpful to the students. He had office hours everyday which helped immensely and was always willing to answer whatever question no matter how stupid. Chem14Cl is notoriously a hard class but taking it with this professor made it one of my favorite classes since I felt like the work I put in directly correlated to how I did in the class and the professor and TAs I interacted with were all kind and helpful. I appreciated how he always came to check on how the labs were going during lab periods too. Also the study guides are very helpful and I really appreciate the detail put into them. If only every professor was like you Pang, I'm gonna miss you <3 Also thanks for the candy on halloween and during office hours :)

Prof. Pang is so nice and funny and clearly cares about his students. Labs and reports were tedious but mostly just busy work. Fairly easy midterm and final as material is mostly from 14A and B. Definitely recommend this professor and taking it during the summer.

Amazing class! Definitely recommend taking this concurrently with 20B as it definitely helps bring the concepts to life.

The class is a lot of work- you have weekly prelabs, postlabs, a small "essay" later in the quarter that provides extra credit as well as midterm and a final. However, the work isn't necessarily difficult as long as you follow all of the instructions and maybe even check with your friends. Stay on top of things and you'll be fine!

Pang is so nice, engaging, and genuinely cares about student learning. He prints out all the lecture slides so if someone grabs you one you don't really need to go to lecture. Lab attendance and PPE is very strict though. Overall, I would say this class is easy it's just a lot of busy work. Tests are fair and simple if you've taken 14B recently and with a good professor.
