Quarter: Fall 2019
Grade: 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.

I wish to write this review in order to help future generation students, either you are math/stats/science majors that require this class as an upper mandatory course or you need to take this class for some reason. Through talking about the big picture about professor Huang, her grading scheme, grading standard, lectures, homework, etc., this review may help you decide whether you should take or continue on this class or not.
-
About Grading Scheme: 25% Homework + 25% Quizzes + 20% Midterm + 30% Final. OR 25% Homework + 25% Quizzes + 50% Final, Professor will eventually choose the higher one among these two that calculate towards your final grade, which means it is possible to miss the midterm and increase the proportation of weigh of you final. There is also 1% bonus point on your final grade if you do the evaluation at the end of the quarter. For the quiz and homework parts, professor will drop 2 lowest homework scores from the 7 homework scores, and drop 2 lowest quizzes grades from the 7 quiz grades. Initially the A cutoff is 93, but professor Huang said the grades may be curved according to the absolute perfomance of the entire class, so no need to worry about the 93cutoff.
-
About Midterm: There is only one in-class 50-minute-long midterm that takes up 20% of your final grade. The time of the midterm is quite late in the quarter (roughly week7) and will cover the topics mentioned on the studyguide. Professor Huang always give us a studyguide for exams, including midterm and finals, which are extremely helpful. Make sure that you understand every single question on the studyguide. Midterm is overall fair, consist of 4 , where the difficulty of midterm questions are very similar to the homework questions, relatively easy in general.
-
About Final: The final is absolutely a disaster, and is the only challenge throughout the entire quarter. Those final exam questions are far harder than the homework sets, and are not similar to the studyguide questions at all. Those unbearbly difficult questions make the average of the final drop to 58.8%, where the midterm average is about 76%. If you do not study very very hard for the final, spend enough time practicing studyguide questions, you might get screwed on the final. I'm a math-major student and still spend 60 hours in the previous week before the final to practice, and I still think the final is VERY DIFFICULT. Both midterm and final questions are not the same questions you did in homework or in discussion, while I heard some other professors use exactly the same hw questions on exams. So if you are not that confident with your performance in this extremely challenging final, try other professors' sessions instead.
-
About Quizzes: There are in total 7 quizzes throughout the quarter, starting from week 3 to week 10 (midterm week no quiz). The lowest 2 quizzes will be dropped. These weekly quizzes are very easy, which are 10-minutes-long conducted during discussion sessions every Thursday, consist 1 proof questions. All these question come directly from the homeworks, and are exactly the same questions. If you do the homework, then this should be just easy pz for you.
-
About Homeworks: There are in total 7 homework sets in total. The lowest 2 homework grades will be dropped. Each homework set consist of 2 sections: The first section is the graded question section, this is the one that will be graded, which consist of 3 questions from the text book. The second section is suggested question section (not graded, no need to write down), which is made up of lots of suggested homework questions from the text book assigned by the professor, which are helpful for exams. Doing the suggested part before exams can really help you do better. Overall, the weekly graded section of the homework should take you less than an hour.
-
About Lectures: All the lectures this quarter are podcasted and posted on Bruinlearn website. Professor Huang also posted notes for every lecture on the website as well, which are very helpful. During the lecture time, all professor did was writing the notes, so it is possible for you not go to the lecture at all (I went to the lecture only once this quarter) by just reading the notes/read textbooks/watch recordings. You can choose from either one of these approaches. Perosnally I think Professor Huang has a very thick accent, so it might be more efficient to read through the textbook and notes by yourself instead of going to the lecture (Textbook is far more comprehensive and self-explanatory).
-
Overall, the grading scheme is very friendly (easy full mark on HWs and Quizzess) which the proportion of exams are not that high. You wont feel that stressed as workload is evenly distributed throughout the entire quarter. Homeworks and Quizzes are very easy, while Midterm is also very fair and straightfoward. The only challenge is the final, which needs great devotion and time spending on preparing for it. Generally speaking, Huang's Math115A is fair and I would recommend to take hers for future generations~

Quarter: Fall 2019
Grade: A

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.

Quarter: Spring 2020
Grade: A

Dr. Huang is an excellent teacher.

Her lectures are hard to follow if and only if the students don't give her any indication whether they understood what she meant. Whenever any student asks any questions, she is patient enough to answer the questions in details. Also, do not neglect the office hours! She is willing to answer any questions you have regarding the course material, and she can even guide you through if you have any troubling about learning math in general.

She has been getting feedback from her students consistently throughout time and is making progress that everyone can see. Maybe she is not the best lecturer yet, but she has been improving a lot even in the same quarter, so I believe she will become a famously excellent teacher very soon.

Also, for a non-math major, math 61 deserves one's time. As most people know, math-61 is not intended for only math majors (it is a CS major requirement), and the course difficulty has been decreased astonishingly from what one should expect from a course in discrete math, which is math-180. Math-61 covers a lot of basic concepts that were usually assumed knowledge of in a math course intended for math majors only and cannot be more friendly to non-math people. What is difficult is NOT what the professor covers but what the concepts are actually are. One should not blame an instructor simply because a course that is intrinsically difficult was taught.

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.

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.

As someone who took both Math 33A and 61 with Professor Huang, I can say that though she can definitely continue to improve the clarity of her lecturing, she’s overall very nice and helpful, and I recommend taking math classes with her. She’s always responsive through email and willing to answer students’ questions. The homework, quizzes and exams are mostly straightforward, manageable, and come from the lecture examples. An easy A if you put a reasonable amount of time studying and doing the work required.
