This class is EASYY but overall just alright. The professor is kinda dry but overall still kind and willing to help. You can honestly just read the textbook alone and be more than fine in the class. HW was not too bad but is graded so make sure to double check especially with the ones that have provided answers from the end of the TB. The exams, however, can be tricky. You’ll be given just an IR, for example, but not the molecular formula. BUT!, best thing about the exams are that they’re completely open note as in, I had my iPad notes and laptop for the exam.
As for the lab, it’s fine but disorganized at times. The TAs are a great help and getting good results isn’t expected. If anything, sample data is given if your experiment doesn’t work (and a lot of them don’t). The lab reports are really straightforward and doesn’t require a lot of explaining. Literally just analyzing your NMR in bullet points; they’re not graded that harshly + a lot of time is given to complete them especially since we would finish some of our labs in less than the given lab sessions.
The grading scale is also crazy; 75% for an A-, 50% is a B- so you’ll literally be fine.

The class is fine; rather, the overall experience has been very positive, if a bit disorganized. Some of my peers took his 30B and 30BL class and he's really kind and knowledgeable in NMR spectroscopy. He's also very flexible and open with any suggestions and scheduling so be aware of that. He moved lab report due dates and allowed a take-home final exam for convenience. His teaching is decent and also funny too.

Personally, I don't attend the lecture section often since I have research at that time but my friends and peers say that the lecture didn't help out as much as they wished. I hear office hours is much better though, so take advantage of that and the really good textbook. Since the lectures can be a bit dry and slightly disorganized, you'll be lost in some portions of the HW so I highly recommend starting it early. The midterm is tough but nowhere near as horrible as other chem classes tbh, the average was 87% and the lowest score is 70%. The final exam is extremely difficult but it is take home (by request). The grading scale is very generous, with 85% being an A and 70% being a B.

For the labs, many of us haven't done organic chemistry lab or research in a while so expect to be slow and rusty. You got a lot more time than you think and it'll be way better in Winter as rn there's 15 people per section so you have to fight for space/wait a lot more lol. Lab 1 is super easy, Lab 2 is really challenging, Lab 3 is fairly straightforward (as long as you pick black pepper or unknown 2), Lab 4 is quite straightforward, and Lab 5 is moderately challenging. The four TAs this quarter at fantastic and very understanding, so make sure you ask lots of questions and get to know them personally. Emma and Lily are sweet people and encouraging so I highly recommend those two if you can get them. If you work with Jacob and Aris, you will be very proficient and well-rounded in your techniques so you can't go wrong with either TA. My tip is be prepared ahead of time, be familiar with the expected techniques, ask lots of questions, and work well with others in hw/lab so you can make your experience much better.

Overall, I really enjoy this class. Despite the class and experiments overall being a bit disorganized and occasionally being frustrated, this class does not take a significant amount of time and you have a lot of room for error. Thanks to the TAs and the grading scale, I did not stress much in this class and I really learned a lot of useful organic techniques and solving skills that I will apply to my organic research.

very mid class, mostly review from 30 series + few other things (literally missed last 4 weeks of lecture and still did fine in the class). The labs are a bit disorganized and not updated and some straight up didn't work. Dr. Rubin himself is incredibly nice and understands this however so the class itself never feels stressful, mostly just annoying at times.

exams are a very small part of your grade with mostly lab reports (which are just kind of worksheets which saved a huge amount of time). don't let the 2.6 rating or whatever be a turnoff it's just that there's nothing special about this class

A pleasant professor - not the most interesting lecturer, but he conveys the information just fine. Labs, thanks to the TAs hosting them, were straightforward and good review of core skills, including structure identification. Some stumbles as it's been years since previous lab course, but TAs were very understanding and generally constructive about the whole situation. Some problem sets (more structure identification) were tough, but never demoralizing. Midterm performance was unexpectedly spread out for currently unclear reasons.

Professor Rubin is really a nice guy who concerns student's learning. His lecture is very fun and enjoyable. For his midterm and final are resonable. This lab is the most interesting class that I took in UCLA.
