Professor Clubb is very chill and extremely helpful. I went to as many office hours as I could and he basically tells you what going to be on the exams, he also gives you his past exams and then reuses questions on past exams. It may be annoying to have a quiz every week but it was actually helpful because it forced me to be on top of studying. His class was not that hard and I feel like I learned a lot especially about real life scenarios.

At best, Dr. Clubb is mediocre. The only reason he has been getting good reviews is because he hands out grades that are better than expected to a substantial number of people. His grade distribution philosophy is horribly, I stress, HORRIBLY thought out. For ex. if the total work you have done in class is (everything,. i.e. homework, midterm, quizzes, etc.) is out of 100, then the grade distribution will be something like this:
60-80: B
80:81:B+
81:82:A-
83:100: A
He thinks it would be fair to reduce a student's grade points for that subject from 4.0 (i.e. A) to 3.0 (i.e. B) for such a negligible difference in achievement in class. It does not seem to be well thought-out.
Professor Clubb is not a good presenter. His lectures, (and thoughts) are usually too dotted. (You know how some professors make everything they teach perfectly interlinked? Prof. Clubb's lectures can't nearly achieve that.) His tests are identical, in most cases, to those administered in previous years. So if you, like the rest of this school, are not very keen on genuine learning, (which, of course, is fine), then you shall find this class pleasant -- moderate workload, mostly hassle-free. But if you are, like me, constantly looking to be intellectually challenged, intrigued and marvelled by what is being thrown at you, then you shall be truly disappointed with this class.

Random points:
Some questions (especially on the finals) test you on absolutely MEANINGLESS details.
Quizzes administered (3 total, best 2 counted)
2 Midterms, 1 Final
No Homework
Presents lectures through slides.
Is approachable.

In sum, Dr. Clubb is not a great educator. I am confident that Dr. Clubb is an exceptional researcher-- otherwise it is hard to be faculty at UCLA. But ideally, someone who truly cares about teaching should be teaching this intro class.

I've heard plenty about the dreaded 153A course most pre-meds are required to take, and decided to take it over the summer so that I would be able to just focus on one class. After looking at Clubb's reviews, I decided to take it with him. The class itself is very difficult, but Clubb does try his best to tell you what exactly will be on the exam (what you have to memorize and what you shouldn't waste your time memorizing). At the beginning of the course, he told us that the average was going to be around a B-. The averages on the first and second midterms were 69 and 64, respectively, which was still surprising for me. I got an 86 and a 69 on the midterms, and the final was pretty difficult because it had so much detail. In the end, I got a B (I feel like I should've gotten at least a B+ or an A- since the averages were so low) but whatever, it's biochem. Clubb is a decent professor, it's just the class that's really difficult. I'd suggest taking him, just be prepared for a lot of work

Took 153A with Professor Clubb. I thought he was a pretty effective lecturer and his office hours were very helpful. He prints out the lecture slides and hands them out, which I appreciated. His lectures are quite entertaining since he makes a lot of corny but funny jokes. He also lets students post questions on ccle which he answered everyday, which was very helpful. There's also problem sets and past exams on ccle, which really help you when you're taking the midterms and finals. I think he has changed a lot since the reviews below. He was very clear on the material that would be tested on, and doesn't test you on unimportant minor details like some reviews have stated. I thoroughly enjoyed Chem 153A with Clubb.

Professor Club is a great professor. He is funny, approachable, and connects with his student. He tells you straight up what to memorize and what not to. After taking his class this summer, I say his teaching style revolves around molecular mechanisms and a few chemical/structural names. Knowing general concepts will help you score points on his exam also, but no need to know it to the level of detail presented in the book. I personally am not a biochem major, but after taking his class I decided to continue on to 153B. After far as midterms and the final goes, he usually post old mid term/ final question on VOH, and it would be in your best interest to do them. The average for midterm 1: was around a 65% and midterm 2: was around 68% or so. Overall, since its biochem, you will be required to put a lot of work into learning the stuff, but aiming to get an A or a high B is very possible.

This is the only chem class that I have truly enjoyed. Clubb is straight forward. He teaches you only the things you need to know - the important things. Everything that he has taught me has come up on the MCATs. I am not sure how the other teacher (Bates) teaches her Chem class. Take Clubb, you will probably learn a lot better and understand the topics instead of having a chem teacher cram your brain with too much useless information. Also, you will get a better grade in Clubb if you just go to the lectures and pay attention. (he tells you what will be on the test basically and also, you can ask him "Is this going to be on the test" - great isnt it?)
