I don't know why people are hating on Henary. His class was pretty straightforward, he was pretty eager to help in his office hours as well but no one showed up most of the time. It will probably be 10 times harder in person tho not gonna lie

Henary tries to engage the class in his lectures, but honestly, his accent is somewhat hard to understand (you really have to pay attention to pick up on what he's saying). To make up for that though, his lecture slides pretty much give you what you need to know for the midterm/final. He does however tell you some things in lecture that are not on the slides, so be sure to attend lecture to pick up on those things (they definitely show up on the exams!).
The labs themselves are alright, but they were kind of long and tedious (lab twice a week for 3 hrs each). The soil project at the end of the quarter was pretty daunting at first, but as long as you explain what you did in your lab report, you should do pretty well on it (my TA supposedly gave most groups A's on their reports). Overall, it wasn't a bad class - just a lot of tedious work.

This class is tedious, where the consists of two long lab blocks and continuous lab write-ups over and over which are graded pretty harshly if your numbers are off. This is a majority of your grade and takes up a significant portion of your time. Furthermore, Professor Henary's lectures are extremely difficult to understand, as his accent makes the class almost incomprehensible, if it wasn't for his slides that are more clear. The tests aren't too bad, but the final featured a significant amount of spectra analysis, which if you are not taking Chem 30B alongside or before may prove difficult.

Legit could not understand a word this guy said the whole entire time. I recommend coming to lecture, grabbing the notes and ditching. If you had AP Chem experience and you did well in Chem 20B you’ll be fine. The final is a little harder than I was expecting though - so you do need to study for that.

It's best if you avoid taking the class with Henary. He is not a great lecturer and runs through his lecture slides relatively quickly. While some of the topics are not too difficult, Henary's explanations make them confusing and difficult to follow. I would suggest taking the class with another professor who gives clearer explanations. Henary does a poor job at preparing students for exams because he does not provide sufficient practice material. At most, you get a practice midterm exam and practice final exam. Even then, numerous answers to the practice exams were wrong. If you do take the class with Henary, I suggest joining the class group chats so you can find the correct answers to practice materials or taking another professor.

His accent is VERY difficult to understand. He reads the notes for his entire lecture so just grab them and read them on your own time. Office hours are helpful and Maher makes sure you understand the concepts of the prelabs/postlabs. The lab itself was very enjoyable and you will be able to finish early most days. The final is fair and you're allowed a cheat sheet which makes it super easy. Attend the review session before the final as Maher goes over crucial information, and the final basically decides your overall grade.

20L is quite basic: titrations, acid-base, spectrophotometry, distillation/gas chromatography, stoicheometric analysis. Not very difficult, easy to find information online. Make sure to ask your TA about everything and anything since they are the ones ultimately grading your lab reports.

Maher is boring and hard to understand. However, he has handouts in the front of the class every lecture which are important and helpful.
Exams were OK, with a few bizarre/difficult questions.

Terrible, terrible required class. The UCLA chem department needs to revamp it. Or at least get Henary to stop teaching. He's often abrasive and doesn't answer questions well. Glad it is online and lecture isn't mandatory.

This was my last STEM class at UCLA after being an LS major, where I loved the rest of my classes. You can learn some stuff about chemistry, but mostly the class focuses on doing stupid lab reports and getting assignments in. Really bad. This class kills learning.

Anyways, that's my rant. You probably have to take this class for med/grad school, so good luck. Get your hand on previous exams and lab reports for practice and examples and you'll be fine. My TA was Yuting Miao and she was chill. Just kept us really long for some of the labs.

btw they're changing all the labs, you might waste your money buying old labs.

Professor was always extremely unclear and unhelpful. The directions on the labs were often very confusing. The material wasn't difficult but this class required so much time for tedious and useless lab reports.
