The professor definitely seemed to try his hardest. He isn’t the best lecturer per se, but if you can understand his accent, his lectures are generally useful. So, I’d go to them. Also, Henary always had extra office hours, which was convenient.

The class is like 20al in terms of rigor, and is basically a watered down combo course of 20b and 30b. That said, the workload is definitely heavy at times, with two lab write ups per week. Also, some labs take rather long to complete, but usually they are fairly interesting.

The class itself is easy; 50%+ of his students get A’s for a reason. During the midterm you’re given all formulas, while during the final you get a one page cheat sheet.

Students only need the lab manual. The other book that isn’t the lab manual is basically useless for this class, and basically a waste of money.

Henary grades like Pang’s 20L class but his lectures aren’t as good though.

Enough said about his accent in other comments. Other than that his lectures are fair and useful for exams. Like every other lab class, the workload of the class is painful even though it is a 4-unit class. Every week you will spend ~5 hours in the lab alone, plus 1 hour in lecture plus ~9 hours for lab reports. I know you will be second-year when you take this class and you will have 22 units, but please do not take full 22 units with this class as I did.

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.

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.

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.

Henary's reputation isn't great, but he's actually a pretty good professor. He truly cares about students learning and he always wants more people to come to his office hours. He's pretty lenient in general and isn't a stickler like other chem professors. Our midterm was a bit hard since grading was a bit harsh but the average was around 78% I think and he ends up scaling it in the end so you should be fine as long as you get average. You get a cheat sheet on the final which is amazing since no other chem lab professors let you have one for the final, and it pretty much will let you get a good grade on the final. There's a lot of work for the lab but it's pretty much busy work and it just sucks being in lab for 6 hours a week with multiple prelabs a week sometimes. Still, Henary is a great professor and I would definitely recommend him for 30AL.

I liked 30AL, looking back I think a lot of the labs covered experiments that were interesting and useful to know (separation/extraction, purification, TLC, ion-column, a bit of analyzing spec). Taking this class with/after 30B is helpful for the units on mass spec, IR, and NMR, which had a couple of dry-labs dedicated to those concepts. Like all lab classes, your experience depends highly on your TA.

The lab reports are more frequent than 20L, but seem to be a bit shorter in length, which is nice. The independent experiments aren't too bad, but I was definitely pressed for time on one or two of them. Soil lab was very doable, but it does help if you know someone who took the class before.

I found the midterm/final to be a little difficult/tricky, despite the midterm being open-notes and the final getting a cheat sheet. However, the class is pretty doable, interesting, and it's not too hard to get an A.

Took this virtually so it was very easy. Henary is not a great lecturer, he just doesn't explain things very clearly or in a logical order. Your experience is probably going to depend mostly on your TA

Not a fan of the class in general, Henary was fine though. The labs are annoying, but it's not that much work as long as you stay on top of it. Henary tells you how to do parts of the pre/post-labs in lecture and tells you things that are going to be on the exams so that'd be the only reason to go to lecture.
