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

I took this class during the pandemic so there were obviously a lot of changes pertaining to conducting the actual experiment. Therefore, we watched lab experiment videos during the lab. The workload got a bit tedious at some point but as long as you stay on top of it, you're good. Understanding specific instructions from TAs would help since they are grading. He did not test us on any foreign subject which is great. The midterms and finals were fair. Overall, a pretty good class! The professor is kinda quirky which is funny :)

We took this class online (lol) so it was quite odd, but it thankfully meant that we didn't have to do any of the labs. Some of the post-labs are tedious, but both the midterm and final were not too bad. Make sure you read the slides, do his practice exam, and do the pre-lab questions before the exam and you'll be in good shape. Also it's very dependent on your TA so make sure you get on your TA's good side lol.

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.

I love Professor Henary! He did have extremely heavy accent, and made me frustrating for the first few weeks. However, his English is understandable, and you will get used to it (from the perspective of an international student who is not an expert in English). He explained the concepts very clearly, and he often repeated what he thought is important, and he also spoke slowly, so it's not hard to follow him during the class. His lectures are engaging and inspiring. The pace of the lectures was alright.
His texts came directly from the slides. Midterm was EASY. Final was harder, but was fair and doable. I believed everyone did worse than the midterm, and he curved anyways, so not bad.
Overall, 30AL offered by him was a great class. I prefer Professor Henary over Pang, just because Henary spoke much more slowly than Pang, and his tests were much easier.

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.

I think myself and the past reviewers have something in common: we're not quite sure how Henary is still employed by UCLA. He's horrible at his job. TLDR: Wait until you find some other professor to take this class.

Not only does he literally read off his lectures, but they provide no useful information. 90% of the class did not end up going to lecture throughout the quarter because YouTube did a better job at explaining. He explains things in the most confusing way possible, and he loves being condescending towards students. Sometimes, it feels like I'm being targeted by him just because I didn't understand something quite well. Most students never show up at his office hours but take up the entire block for TA's. Luckily lectures are not mandatory, although he highly encourages them for some reason.

For the midterm, we got a 76% average as a whole class. It got a point where he just started providing free regrades. Yet, even still, he would not want to give points back for some reason. He expects you to use certain formulas and methods when solving problems, but never explicitly mentions them on the test. Points were taken away from me just because I used an alternative method to solve a problem, that still, showed all my work and gave the correct answer.

On his practice tests, you just get the answer without the working out. How else are we supposed to know how to solve questions. Luckily the TA's for this class saved all of our grades during labs and office hours, but this review isn't about the TA's or the class.

If UCLA ever reads this, please consider someone else for these lab courses <3. It's essential because at the end of the day, the skills we use here are going to be used in our future fields.

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.

Professor Henary's lectures are not very engaging and are often confusing. Sometimes he will explain a simple concept but will make it seem complicated. However, Henary lectures slides so if you know what's on the slides you'll be fine.
The TA's in the class all grade differently which can be frustrating when you are trying to solve questions for the lab reports. I luckily got a more lenient TA but I know there were TA's that were more strict. The prelabs are usually pretty easy and can be finished quickly but the post labs definitely take some time so don't procrastinate on them. The post labs take long sometimes not because of solving the problems but because you have to figure out what is expected of you.
There is only one midterm and Henary does not tell you what you did wrong. You have to directly ask your TA where you missed points. If your test was graded incorrectly you would never know. The midterm and the final are reasonable and grades balance out if you get good grades on the lab reports.
Overall, this class with Henary is okay. There are definitely some complaints but it is very doable and not too difficult. You can definitely learn to work around the issues in this class.
