His classes are very logical and clear, I like that he offers recorded lectures. I didn't do any homework and took the exams just by listening to the lectures, so I don't think his exams are very difficult. Even though I don't like to do challenge reports he assigns, it's really kind of a free credit. Overall, I recommend taking Wong's class.

Richard Wong is a very good professor, and I would definitely recommend his class.

When I took it, there was a dual grading system that kept the better of two possibilities (allowing one midterm to be dropped, like many math classes here). Both grading schemes had four components: either one or two midterms, the final, six quizzes, and two 'challenge problem sets', which were somewhat akin to guided research papers.

The quizzes were designed to be more of a review of the previous week than an examination, so the questions were both reasonably straightforward and graded leniently. The challenge problem sets were a bit nebulous in terms of expectations, but I personally found them interesting and the class averages were high. Both of these assignments allowed students to collaborate, as long as the work they turned in was their own.

The midterms and final were very well written, including content that had been covered in class (no curveballs), but requiring some thinking - more than just memorized problem types. During my quarter, they were 24-hour exams, but could potentially have been a bit tricky under a time crunch. Homework was not collected.

Wong himself is friendly and approachable, and he was willing to slow down if students had questions. While his lectures could be a bit boring, they were both clear and useful. Attendance was optional.

He didn't get through all of the material and I didn't really retain anything. Ez class, but I am praying for myself as I go into 32B. Im gonna die probs. wtf does the gradient mean

Wong is a superb lecturer; I'd take him again for any math courses. My favorite class of the quarter. Tests are doable but not super easy.

Overall, the class is above average. Wong is a great professor with a high level of organization, and he does his best to make the class as accommodating as possible. He records his lectures on Zoom with his annotated notes, so if you are ever confused in the class, his notes are always there. His style of lecturing is extremely clear and concise. He explains everything conceptually too, so there is a backing for everything that he teaches. He does a Zoom review session before every test to make sure every student is as prepared as possible. However, the homework is not graded and is optional, so you will miss out on easy points. Wong is unique in having the class do 2 challenge reports, which is where you write up a textbook solution to a difficult real-life application. This is pretty cool, but the reports are moderately time-consuming, butthey do reinforce the topics of the course. They are a big portion of your grade though, so if you spend a lot of time on them, you will be rewarded. The exams can be tough and confusing. The first midterm was crazy difficult (got a 40%) and not like the practice midterm at all, but the rest of the tests got easier and were more in line with the expected difficulty and fair. The tests were graded leniently, with a good amount of partial credit given. Some extra credit is given, and you can use a flash card for the exams, which is good. Group quizzes are also a good chunk of your grade, so make sure you get a 100% on them.

TDLR: Dr. Wong is a great lecturer, professor, and person. Extremely understanding.

Class is fair, my grade was expected, maybe even better than expected.

Wong overall was a good professor. The workload is really nice: no homework required, only group quizzes are graded (so you almost always get 100% on quizzes and will actually learn things from the individual portion that isn't graded), and 2 challenge reports. The challenge reports are pretty straightforward, all you need to do is work with other people and attend office hours if you can't figure out a problem, and explain every step of the solution thoroughly in your report. You can also request a regrade for your first challenge report. Wong posts records all his lectures and provides his annotated slides after class, so you have all of his material, and his office hours is pretty helpful for asking questions and solidifying concepts. He encourages participation in his lectures and is a very chill and gentle professor overall.

The only difficult part of his class are the midterms and finals because the practice materials he provides are much easier than the actual tests, so basically the only way to prepare for them is to practice the hard problems from the textbook. Almost everyone in my class underestimated the first midterm and didn't do well, and I think Wong noticed that and made the 2nd midterm easier, as the class average shifted from a 68% to a 80%. He does offer two grading schemes as well, where only the best midterm is considered for your grade, but the challenge report and final is worth more than usual, which saved my grade in the class.

I thoroughly enjoyed taking this course with Professor Wong. His lectures were extremely clear and at no point did I ever feel like I was being left behind. I would strongly recommend taking this course with Professor Wong.

I appreciated that his lectures and review sessions were all recorded and posted on BruinLearn, along with all the notes/slides, which made studying for tests more convenient. I still showed up to almost all his lectures in-person; I think he lectures fine (it was pretty common for people taking 32A with another prof to come audit our lectures), but personally I got bored and distracted at times because it can feel kinda slow, and the few times I missed class and had to watch the recording afterward, 2x speed was a perfectly comfortable pace. But still, I'd recommend going to class in-person (and don't put off watching the recordings if you ever do miss class, especially in the later half of the quarter).

The homework is optional, but I'd highly recommend doing it. I downloaded a free online copy of the textbook which didn't have the answers (and I probably would've been too lazy to check my work anyway), but even so, just doing the problems and knowing that you generally know how to do the problems is helpful. I tried to do the homework before the lecture and also read the textbook section before doing the problems, so I never really felt lost during a lecture (which I know some of my classmates have). If you get behind on homework it's not that big of a deal, but I'd still recommend skimming through at least a few of the assigned problems to see if you can do them or not.

Discussion sections were probably where I learned the most. There are group quizzes (which you can make up on your own if you ever miss discussion) that you first take individually and then discuss with an assigned group for the quarter, which was probably the only time I really talked to my classmates (talking is scary okay), but I liked working with my group. Most of the quizzes were quite easy, and the couple times they weren't and our group couldn't figure it out, I understood after the TA went over it.

Another part of the class are the two challenge reports, which I actually kinda liked. They weren't too difficult, just time-consuming. Generally, you'll be able to get all the solutions to the problems during discussion section, and you just need to write up the step-by-step process of how you got there within the next week. I used LaTeX just because I already knew how to use it, but I'm pretty sure handwriting is the fastest way. I know some people who used Google Docs or other word editors, but at that point if you're already dealing with tedious math typesetting, might as well learn LaTeX.

The first midterm surprised me in terms of difficulty. It was my first college midterm so I was at least a little nervous, but I also felt like the content we'd covered in those first couple weeks was simple stuff (though I'd learned about dot products and vectors before in high school). In terms of studying, I reviewed the slides and the summaries of the textbook sections covered for maybe an hour before the exam, as well as the practice midterm he posted the week before. The practice midterm was super easy so I thought the actual midterm would be similar and... ahahahahahaha. Not even close. I kinda panicked during the exam when I read one of the problems, but I eventually figured out how to do it after like 15 minutes of staring at it. I think it was tricky in the sense that preexisting mathematical intuition was probably what made the difference and not exactly the explicit content of the course that someone would study for (at least for that problem, though it was definitely still on-topic and relevant)? I still ended up acing the exam, but the class median was like a 69%. There's no curve on exams (but possibly a curve on the final grade) so... I think this served as a substantial source of distress for many people throughout the rest of the quarter.

The second midterm was much more reflective of the practice materials we got, and though there was one concept (freaking squeeze theorem) I was kinda weak on before the exam and also during the exam, the partial credit was great, and I only ended up losing a couple points. The class median was much higher for that exam (I think in the lower B range). The final also felt pretty straightforward in my opinion, and maybe it was a good thing I felt challenged by the first exam because I studied more for the later ones.

Overall, I liked this class, and I like the way Prof Wong structured it. His class might be more challenging than that of some other teachers (from what I've heard), but I think it's worth it because I feel confident in the content of the course now. Granted, I did not have to participate in the stressing-over-grades part, but even so, I wouldn't let that be a deterrent to taking his class. Though I've never gone to his office hours, he seems genuinely approachable and is a pretty accommodating professor: with two different grading schemes to help you get a better final grade, time banks for turning in late challenge reports, organized notes/slides posted on BruinLearn and convenient make-up policies if you ever miss lecture/discussion, a little bit of revision and extra credit opportunity, and possibly more I'm forgetting that you'll see in the syllabus. In any case, this was probably my favorite class this quarter, would rate it a 9/10 experience.

32B is considered one of the hardest lower div math classes here at UCLA. I would even say it's the hardest computational lower div math class. It really has nothing to do with the professor. The class content was just hard.

The class is consisted of 2 midterms, weekly discussion quizzes, and 2 challenge reports. The weekly discussion quizzes are group quizzes, so you collaborate with other students to do it. Getting a good group with collaborative people was really important to get full score on the quizzes (or just pray one of the group mates knows everything and can carry everyone else lol). The challenge reports are usually longer problems where you have to do textbook style write-ups. Just explain your answers with detailed words and say why you did so and so. Usually, getting full score on challenge reports are pretty easy. You are also encouraged to use resources including the textbook, lecture notes, other students, the TA and the prof (just cite where you got your information at the end).

Overall, I think this class is alright. I definitely spent a LOT of time studying for the final and I didn't particularly like how homework was not required. You are still encouraged to do it but you just don't have to turn it in. There was just no motivation for all of us to do them so we missed a lot of practice opportunities.

Professor Wong is very organized and a clear lecturer. He has very clear expectations and his exams are fair. However, there is no "easy" part of your grade; homework is not required, but he does make you write two challenge reports which are like essays explaining how to solve different math problems. Overall, I appreciate his clear teaching style and would take again.
