Quarter Taken: Fall 2019 Submitted Nov. 19, 2019 Grade Received: I

Being in her Math 33A class right now, I think that some of the other reviews were too harsh. To be clear, I don not think she's a good professor, but she's not as bad as others make her out to be. Her two midterms so far have both been fair and averages on the first and second were a 83% and 76%. She assigns a decent amount of work. She just isn't clear at all on explaining most concepts. I go to lecture and I get more confused than when learning from the textbook. Overall, I don't recommend but I don't think that if you have her it's the end of the world. She might not explain things super well but she is still knowledgeable and has answered my questions pretty well. Also her accent isn't that bad, but writing small on the board did impact her teaching in the beginning a little bit. Also, math 115A people shouldn't leave reviews here because it's a completely different class that is more proof based in itself, which she seems to be better at then giving us physical arithmetic examples.

Before I start, I'd like to comment on some of the reviews that are already posted. If you are making fun of her Chinese accent, please stop. I am sure she knows of her thick accent and understands that sometimes it's hard for students to understand her. She tries her best. Most of you have not learned English as a second language. It's hard. Cut her some slack. As for the Math 115A reviews, do it in your own section. She may be different for different classes. No need to attack 33A and how "it's just pure computations." You took this class before to get to Math 115A, and I am sure you complained when you took it too. Now, here is my review:

Professor Huang isn't very clear with her lectures, but she progressively improved. She understood that students didn't like her absurdly "proofy" homework assignments (which were very long BTW) and changed that by assigning more relevant problems. I believe this was her first time teaching at UCLA, but she adjusted pretty quickly after seeing what was not working for the first half of the quarter. As for her grading, she is very lenient. The midterms were reasonable and they were graded fairly. The only complaint I have is that the second midterm was bit of a time crunch. As for the final, it was pretty difficult in my opinion. Without calculators, it's pretty tedious to do (4/3) + (7/11) and such, and since I messed up a calculation, I could not finish the exam as correcting my mistake took up a lot of time. She did pull some unique tricks on the final and I think if I didn't run out of time, I would have gotten most of them. As for her curve, she is VERY generous. She curved very heavily and gave a lot of "A"s and "B"s. One thing she can heavily improve on is that she has both homework assignments and quizzes. It would be better if she only has one of the two. Perhaps, she should have quizzes and not collect homework assignments.

Overall, Professor Huang is in no way the best professor for 33A. If someone better is available, definitely take their class. But, if you happen to take Huang, it's not the end of the world at all. I know she will improve.

Dr. Huang was not a very good lecturer, but it was also her first quarter here. I didn't go to office hours, but my overall impression was that she tried her best to be helpful outside of lecture.

Her notes weren't very relevant to 33A material, as they contained lots of theorems and small proofs or a brief explanation of those theorems (as opposed to 33A's very computational focus). I feel like she would definitely be more effective at teaching smaller, upper-division classes simply due to the nature of the material.

Although moving her to a different lecture hall wouldn't have solved all of her problems, I feel like placing her in Moore 100 magnified her mistakes. The slope of Moore 100 is fairly gentle (as opposed to 4000A), and the whiteboards are not raised above the seats (like in Broad 2160E).

Tests and homework were fairly straightforward compared to some of the other math classes I've taken.

ok Huang may not have been the best lecturer but gosh dang it she improved so much over the quarter it has to count for something! admittedly, the first few weeks were rough and I learned everything from reading the textbook. However, after the first midterm Huang started to switch her lecturing style and added more examples which were actually helpful! If you enroll in huangs class actually GO TO CLASS!!! Only 25% or so of our class would come to lecture but in lecture she tells you exactly what to study for weekly quizzes. Also, one time she gave everyone who showed up to class extra credit and gave an example in class that she put directly on the final! Homework can sometimes be time consuming but she only grades a few questions so don’t waste all your time on it. All in all, not a bad class don’t let the other reviews scare you.

Quarter Taken: Winter 2020 Submitted Feb. 26, 2020 Grade Received: B-

She's pretty bad, but as another reviewer has said, it's not the end of the world. Lectures are extremely boring and kind of confusing, but the content is straight out of the book. Also, we only had homework and one midterm, no quizzes, so I'm assuming she changed the class structure from the previous quarters. The midterm grading was fair and the first half of the class was pretty simple, but the second half is a confusing nightmare. Her accent/general manner of speaking makes it super hard to understand which variable, vector, or operation she's referring to, and her notes are often hard to follow. Self-study as much as you can and hope you have a good TA.

Fairly she is not the best professor and this is her first year teaching. She sometimes went over the material too fast with little explanation, but at least she was very willing to help in her office hours. If you don't understand the lecture then go ask her. I went to her OH couple times and I felt pretty useful actually. Lectures are not necessary used in
HW and Exams but they definitely help you understand the concepts. If you are complaining about this class simply because you didn't put enough effort into it, then study hard before yelling in the street. Or if you are thinking about getting an easy "A" on Math 33A, then definitely go find another class. One last thing, for those who attack the professor's accent, please look at the mirror and see how shitty you are.

I took her class in Winter 2020. I worried too much before taking the class because of these harsh comments. But I have to say she is truly a nice person. She tried her best to make everything clear and make students easier. she gives a nice grade policy, once you go to class, do the homework, study her notes, you would be good. She gives fair exams, willing to help during office hours. I would recommend to take her. Seriously

This class was not too bad overall. She didn't lecture very clearly but her exams weren't too hard. I did well on the midterms but not great on the final and still got a B+.

This whole quarter has just involved me desperately searching for youtube tutorials for basically every topic we have covered and camping out at the SMC; thank God our TA has his shit together and is helpful. I don't go to lecture anymore because it's basically just powerpoint slides of theorems and her reading them out loud. Maybe two slides with examples mixed in.

General class details: weekly hw assignments with ~10-15 problems each but varies, weekly quizzes that are SUPPOSED to be covering the hw due that week but sometimes aren't, two midterms and a final. While others have noted the midterm wasn't bad, if you aren't doing well in the class (which isn't unreasonable considering her powerpoint teaching style) and mess up on a few things your score went down a lot for minimal mistakes.

Edit: I returned to class after not having gone for a while, and I have to say she improved over the quarter. She switched from pure powerpoints to working out problems on the whiteboard which was important, and she gave out a lot of hints for the final exam which I appreciated. I would change my warning to not take the class, into a caution to just be prepared to do a lot of self-studying and get a good TA.

She basically does not speak English. Her words are so broken that she might as well be speaking Chinese. Her weekly homework quizzes are not based on the homework and are not easy whatsoever. She does not have a grasp on how to make a class fair as she only says whats on the weekly quizzes one day before the first discussion sections quiz. She basically gives half the class two extra days to study for the quiz. Going to lecture is completely useless. I will say her midterms weren't that bad and were fair if you had a grasp of the information. I wouldn't recommend this professor if you can avoid it, but I heard the other professors are worse so I don't know.
