I took this online. Henary is very hard to understand. It's not just his accent; his explanations just aren't very clear. One of the worst things that stood out to me is when he was going over how to solve a problem on his slides, and he just verbally did the calculations. It was impossible to follow. I guess you can't blame him if he doesn't own a stylus/tablet, but surely with a little effort he could've figured something out. Another thing that irked me, and maybe this isn't a valid complaint, is that he would constantly ask "is this clear to you guys? Hello? Hello guys?" and wouldn't move on unless he got a few replies like"yes makes sense." I know he was trying to get input but it wasted time on already short lectures when we had to constantly tell him to move on. IMO the etiquette should be to listen if anyone says "no I don't understand," otherwise assume everyone understands. On a more positive note, Henary was very accommodating to the lockdown/protest situation. He apparently made the tests easier for us, which was very nice of him. Still wouldn't recommend this professor though.

Now for TAs. I heard from people that they relied heavily on TAs to clarify material. My online TA was Kevin Chandler and he taught us nothing. We joined zoom for 10 minutes, he took roll, and then we left. Even before tests, when Henary told us the TAs would hold review sessions, Kevin didn't prepare anything. He just asked every week if we had any questions. But as TA he should really prepare SOMETHING for us. Also there were two times he was more than 15 minutes late to class. He was a lenient grader on labs for the most part. First day of class, I was like "this guy is so chill that's awesome," but by the end I realized too chill was a bad thing.

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.

Overall, I thought this was a good class that was well accommodated online. Our labs were much shorter this particular quarter because we watched videos of the TAs doing experiments, and based our lab reports from the data given to us. I thought the workload for this class was reasonable. Henary is an understanding professor, but isn't that great of a lecturer as lectures do tend to go at an insanely fast speed (though he does post the lecture recordings so its fine in the end). His midterm/final was also reasonable and did not test on anything not taught during the quarter. If you would like study guides/practice midterms, feel free to email schoolstuffs135@gmail.com

Pros:

- Very reasonable tests. What appears on his tests is definitely not harder than sample problems in lectures and practice exams (which are straightforward already).
- Most of the stuff in his class is really easy if you took AP chem in high school or CHEM 20B before taking this class.
- Only one midterm which is worth only 12.5%
- Pre labs and post labs are worth a lot of your grade (around 20% and 30% respectively) so as long as you spend enough time on those you will be fine in the class.
- Exams aren't open book but you do get to use cheatsheets you created

Cons:

- He doesn't explain things clearly in his lectures so you have to rely on asking TA's if you have questions
- He is unclear abt what he's looking for in your pre and post lab assignments. We were pretty much asking the TA's constantly abt what the prof was looking for in the assignments and sometimes each TA has a different answer.

Suggestions:
- Do not expect to have a good grade without self-studying. The prof is, again, not a good lecturer. But as long as you understand every concept you will have an A in the class.
- Make sure to spend extra time checking your pre and post lab answers they are graded pretty strictly and are worth a lot of your grade.
- When the prof says "listen up guys i want you guys to focus" or "this might be on the midterm/final" during a lecture then whatever he says next is HIGHLY likely to be on the upcoming test.
- Make sure to do his practice tests because they are extremely similar to what appears on his exams.

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 review is relevant to Chem 14BL taken online during the pandemic.
The professor was overall very accommodating of the situation, and he made his final cover only the topics after the midterm. His lectures definitely are not the most clear and you don't really need to attend them to succeed as long as you work out the problems on the slides on your own + understand the concepts. The content is mostly all a review of Chem 14B; the only new information is titration problems.
One problem a lot of students had was inconsistencies in grading since the professor didn't provide a standardized rubric (so the TAs were all telling the students different things). Just make sure to email your TA with any clarifications and don't rely on what other students from different TAs tell you. Overall, my TA (shoutout to Roberto!) was super lenient and understanding.
We have one post-lab and one pre-lab due every week, 1 midterm, 1 final, and 1 CPR assignment. The post-lab and pre-lab is a lot of busy work. I would recommend joining a group chat with the rest of the students. Also if you can find someone that would be willing to share their past labs with you it would make your life a lot easier.

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.

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.

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.
