Chong is a great professor who's able to simplify fairly difficult electrochemical concepts to something more manageable. His lectures were good, and he always made sure to show the practical applications of concepts to experimental design or current research.

In regards to material, the class starts with a fair amount of physical chem. After Week 3, the class transitions from more theoretical lectures to applications, like cyclic voltammograms. If you're interested in chemistry research, this class is incredibly useful, as you'll learn how to interpret CVs from literature and from sample data.

The course only consisted of 3 problem sets and 1 final. As a result, most of the work was concentrated around the problem set weeks. The problem sets were difficult but doable, and grading was lenient. The assigned work complemented the lectures very well, and you'll need to think really critically about experimental design or CV interpretation to answer the questions.

Overall, this is a great choice for a chemistry upper-div if you enjoy physical or inorganic chemistry. Difficult content and problem sets, but it's interesting!

chong liu is the biggest sweetheart I have ever met and I genuinely could not love him anymore. 14B was not hard by any means; I rarely paid close (re: much of any) attention in lecture and the exams were extremely easy, I got a 98% or higher on both midterms and a high B on the final (mostly because i just ran out of motivation and ultimately didn't study really at all at the end) . Honestly 14A and 14B were basically AP Chem and as long as you do the guides and review things Liu provided, you’ll be fine. The quizzes were not hard either, minimal studying garnered me A’s on three out of the four and the lowest of the four he drops. Everyone did relatively well on the midterms and honestly so many people over exaggerate how hard the course is when if you put in some effort and have targeted practice you will literally have to try hard to not get an A or B with Chong. Liu really really tries to help you. The only downside was his lectures were full of proofs and integration that didn't really apply or even help all that much. Basically he's a beautiful soul that babied us through the course. He also ended up curving grades up a couple percentage points in the end to boost everyone's grade a lil extra. also discussion was optional.

Liu is a man of the people 10/10 would recommend
