Very engaging lectures and a great teacher. Has helpful reviews before the tests and lots of office hours for extra help. Cares about students learning and provides many resources. I don’t like chemistry much but found this to be one of my favorite classes.

Deifel is one of the best teachers I’ve had. It is clear that he genuinely cares about each and every one of his students. He makes himself available for all his students to address any questions or concerns. Deifel is funny, engaging, and made me excited for the 8am wake up (I know it’s crazy). He is incredible 10/10 experience.

Deifel is a very helpful guy, holds lot of office hours and is always open to questions from text. Lectures are engaging and Deifel is overall a very nice and helpful professor for what is a class that has difficult material.

He's a very fun professor, he has so many office hours and is free whenever to help students. He's very passionate not just about the subject but also about his students and gets to know almost every one on a more personal level!

Dr. Deifel is a godsend. I cannot express how useful his lectures are, the clarity of his lessons makes chemistry easier to understand. The nature of this class makes it challenging in itself, however, Deifel will hold you by the hand throughout the quarter and answer questions if you show up to office hours. Homework and participation are worth essentially 50% of your grade. Plus, the exams are relatively difficult but straightforward, so you will get a good score if you study. Definitely take this class if you can.

The lectures are important, but it takes personal devotion to truly know the material.

You don’t have to read the textbook to get an A, but you will need to spend some independent time learning in some form (Organic Chemistry Tutor FTW)

Deifel is really funny, and he really keeps the class engaged. Although it is my hardest class this quarter, I always look forward to coming to class.

His review sessions before tests are a godsend. If he didn’t do those, succeeding before tests would be a lot harder for me. The tests are hard, but he puts his best effort into being a highly valuable resource to you. Thank you Deifel!

Deifel was honestly one of the best and funniest professors I've had at UCLA so far. I'm a math major so I had to take a chem class and I didn't know what to expect coming in with a new prof but he turned out to be amazing. The workload is manageable and I never really read the textbooks and did fine on exams. Remember the rules of sigfigs for the exam questions though! The tests are pretty fair in my opinion and Deifel even holds review sessions for each and goes over what he'd tests which was super helpful. Overall a funny and fantastic professor. Would 100% recommend.

Deifel is an interesting professor. Firstly, he’s very caring professor who cares about your chemistry learning and is quite a fun guy. He’s willing to really help his students. He is probably one of the most disorganized professors I have (had him twice). He is really bad with deadlines, class organization and just providing a structure to a class. His lectures are okay but pretty disorganized and half him talking about his inorganic background and half talking about random stuff in lecture. This class is pretty much just TLC and extraction. I would suggest when going to lecture, writing down the things that he says will definitely be on the final and writing down the things he repeats as those are the important takeaways he will probably put on the final. The assignments (postlabs/prelabs) are graded by the TAs and can be a mixed bag depending on who is grading your lab assignment. The final exam is pretty fair for the most part, he tells you what kind of questions he will probably ask. In terms of Lab period, the TAs will absolutely carry your lab experience, your TA will probably be the one who teaches you what you need to know specifically about the lab and how to answer certain questions on the post/pre labs. If you get the goat TA Ben Janda, you are in good hands.

DEIFEL IS MY GOAT. Despite the lab being rather dull (lots of columns, TLC, and waiting, just to get a horrible NMR) and the pre/post-labs being pretty boring, Deifel is an engaging lecturer who really conveys his passion for chemistry. Since nobody is taking this class unless they have to (or they're crazy), I would highly very highly recommend you take it with Deifel.

Some benefits are that you don't need to buy a lab notebook and there's no textbook or lab manual needed, but grading is heavily dependent on your TAs.
