I've had three different math professors at UCLA so far and Wong has been the best. He was clear and engaging in his lectures, to the point where if I missed a lecture I could easily catch up using the recording and his annotated slides (I really appreciated that he posted the slides that he used in lecture for us to be able to markup as needed).
As someone apprehensive of group work, the group quizzes were structured in such a way that it still felt like everyone was doing work (you take the quiz individually first and then as a group, but only the group version is graded).
The practice exams were a bit easier than the actual ones, but overall I felt well prepared for the midterms and final (he allowed notecards which I greatly appreciated).
Wong also offers some extra credit in the form of self-reflections which I thought was a nice way to take into account more than just the exam grades into our learning. Overall, I really liked his teaching and would recommend him.

Such a clear lecturer and understanding person. He sees so much more in his students than their grades, and his main priority is helping you grow as a student. Was a nice change from my 31b course last semester. If I could have a math professor like this every quarter, I would.

Having taken all the lower div maths, I have to say, this guy is by far the worst. His ability to explain material is terrible. And he made us do these 'challenge problem sets,' which literally just involved us getting the answers from the TAs. Not to mention the grading done by the TAs were terrible as well. They graded based on how visually appealing your assignment looked while the content didn't matter. Don't take this class if you want to learn from the professor. Fuck this guy and his saggy tits.

If you are good at understanding math concepts, you will probably like this class. The grading system is very nice. However, if you know you struggle to understand math, spare yourself. I cried before and after every exam, and during every challenge problem set. I think I popped a blood vessel in my eye from crying so much before my final. Every time I went to office hours I left more confused than I arrived. I would think I maybe understood something, and then I'd get to the test and the content would be leagues harder than anything I had done in class or to prepare for the test. If you are good at math, the grading scheme of this class is good because you don't have any weekly homework, only an assignment in discussion, 2 challenge problem sets, 2 midterms, and a final. If you understand the content, you don't have to spend too much time outside of class studying. If you don't understand, prepare for this class to take over every waking moment of your life. You'll go to sleep confused about challenge problems and be haunted by dreams of floating vectors and a 50% midterm score.

The content of this class is very difficult, but professor Wong is your best bet at doing well. He goes at a great pace and explains everything throughoutly. The homework is optional - but I highly recommend doing it and not making the same mistake as me.

I really enjoyed Professor Wong's class. His lectures aren't exactly exciting, but he makes it as easy as possible to get the material. He posted the lecture slides a day before each lecture and posts them with the annotations from lecture again afterward, along with a recording of the lecture. His workload was extremely manageable: homework was never collected or part of the grade so it wasn't required. Doing these problems was definitely helpful for the midterms, but you have the flexibility to do it (or not do it) whenever you want to and at your own pace depending on how good you feel with the material.

The more difficult thing about the class is his exams. They are challenging but very doable and on par with some of the more difficult homework questions. As long as you do the homework consistently, the tests won't be that bad especially since the grading scheme for his test questions is very generous with partial credit. Before each exam, there were plenty of resources to review including a practice midterm made by him with the key posted and another practice midterm by LAs. Additionally, he allows notecards on the exam which was always sufficient for all the material you need to remember.

Discussions were generally pretty smooth. Usually, our TA would review some problem or concept and then let us do the quiz individually, then get us to our groups to finish. Basically, the quiz section of your grade is always free because you get to work with your group plus the next 24 hours after discussion to finish and submit. Our TA's office hours were right after our section so we could always ask him to work through the problem for us.

The most unconventional thing about Professor Wong's class is that one of the main grade components were challenge problem reports, typed up solutions to a set of contextualized math problems. It is a good amount of work and time, but the actual difficulty of the math problems is not crazy. You have two during the quarter and he lets you revise the first one after you get your grade. He thinks of this as a good counterbalance to your grade if you are a weak test-taker, and you should take your time to do well since it really will offset a bad test score.

Wong is a very fair professor. If you learn the material, you will be able to do well in his class. Make sure to do lots of practice, because the optional assigned homework problems are quite straightforward. I'd recommend doing the more challenging problems in the textbook or finding old exams as preparation for the midterms. Wong is helpful during his office hours, as well, so if you need help those are a great resource. Wong's lectures were informative. He records his lectures and uploads slides, and his handwriting is clear and he speaks easily. I attended most of his lectures as I found them helpful. The most time consuming part of this class was probably the challenge reports, as they took a long time to write up mathematically, especially if you don't have much experience writing math papers. Overall though, if you put in the work, you will do well. I was able to learn a lot from this class, and I would take this class again.

No homework, but if lecture doesnt have enough practice problems that it will rly help during exams imo. But the questions he lists are good practice. Discussion quizzes are fair, especially if u have a good TA/LAs. Test are pretty hard, especially if u dont do HW. I failed the first midterm, but was able to do better on the second one and the final, and got a B-, with the second grading scheme.

Professor Wong talks realllyyyyy slowly and kind of dry. But the information is also delivered pretty clearly. Easy to do well in the class due to extra credit and group quizzes as long as you put in the work. Homework is optional but it really does help to do it.

This class is interesting because some people taking it are sophomores and have already taken a few math courses at UCLA while others are freshmen who took calc bc their junior year of high school. As the latter, I found this class on the more difficult end of my courseload, but it was not anything unmanageable. Professor Wong is very down to earth, easy to approach, fair, and makes an effort to make the subject matter as clear as possible. I was nervous going to office hours because he's quieter than my other professors, which I was intimidated by, but in all honesty, he is really nice, and I don't have anything negative to say. As many of the other reviews on here have said, there is no homework grade, so it is all quizzes, midterms, the final, and the challenge problem sets. The TA for this class REALLY MATTERS because of the challenge problem sets. My TA graded super harshly, so I ended up with about 70% on the first set, but after fixing it and completing the second set, which were graded differently, I got 100% on both. My advice for these is to collaborate as much as possible. Use the textbook, slides, and your classmates to make sure what you're saying is correct. You are supposed to work together, so make use of the groupme and campuswire. The thing I struggled with the most were the exams, and in my opinion, it was because they were relatively inconsistent. The first midterm was very easy, the second very difficult, and the final was a completely different format from the first two exams (likely due to the TA strike). It is a challenge to figure out how and what to study because each exam is different. The distribution of material on the final is pretty even, so it isn't like some of the LS classes where focus is put on the last 3 weeks. Overall, I really enjoyed the class, but it was a solid wake up call for what college classes are as an incoming first year.
