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

After reviewing all the comments on her 33A, I'm so shocked, I admit sometime she go through the concepts fast but that's not the excuse for not doing well in the class, and saying she is not a good professor, I mean you can always go to her office hour to ask questions if you don't understand the material, I went to her office hour almost every week, because 115A is a really hard class for me, I usually have some homework questions that I can't solve it myself, and she always really really helps! So I don't understand why the students from 33A have such bad impression on her, in my opinion, she is a great professor who cares students. The weekly quiz is homework problem, so if you do the homework, you are able to do the quiz, and her exams are fair, she gives us review before the exam, so if you don't receive a good grade, blame yourself. Finally, quoting from a previous review :"For those who attacks her Chinese accent, I have two words for you: 垃圾"

I can understand why some peers are angry in math 33A. As a second year I can tell you that math 33a can be cumbersome at times. Still, I believe Dr. Huang did her best in math 115a. One thing I find a lot of people miss is attending office hours. She actually shows you how to write proofs and helps you remember potential mistakes. Finals is very fair, but if you want an A go beyond the homework from week 1 and do pretty much all problems there and you should be good. Don’t be like me doing these problems in the last two weeks because it is exhausting.

Grading: The higher of the two schemes
Scheme 1 - 25% Homework, 25% Quizzes, 20% Midterm, 30% Final, 1% extra credit (course eval)
Scheme 2 - 25% Homework, 25% Quizzes, 50% Final, 1% extra credit (course eval)

Overall, my experience in this class was mixed. Math 115A is inherently a difficult experience for many people due to it being the main transition to upper div math courses, and I think the way Professor Huang teaches the class has both some strong parts and some weak parts. She seems like a nice professor with well-meaning intentions overall, though there are a couple parts of the class that were not great, and some that were decent.

In terms of lectures, I think she was okay. Not the best, but also not the worst. She explains all the material she needs to, but sometimes it's not super clear or she doesn't do a lot of examples to really solidify the concepts for you. She tries to answer all the questions she gets, sometimes her answers help, and sometimes they are equally confusing. In addition, I feel like she doesn't really talk about how to write proofs even though this class is an introduction proofs, she sort of just does them. In this regard your TA might be more helpful, as mine (June Bahr) was. I have heard Professor Huang was more helpful during office hours, but I had a time conflict and was never able to go so I have only heard about how her office hours are and how she answered questions second-hand. If you're able to attend, I'd suggest it.

In terms of homework, the assignments feel relatively low stress in my opinion. She posts a sheet listing a lot of suggested problems, but you'll turn in only 3 questions to be graded so you can focus your energy on getting the right answers on those first before doing practice problems. The graded problems varied in difficulty but with some discussion with classmates, I was able to do pretty well on the homework. Definitely do as many of the suggested problems as you can because they'll be good practice for when you're tested later. Quizzes were usually one question taken during 10 minutes in discussion, and they would often mirror problems from the homework, or in one case the question was exactly the same. Therefore, understanding the homework thoroughly before the Thursday discussion section was key to success. Overall I felt homework and quizzes were fair and not graded too harshly. The lowest 2 scores of each are also dropped which is nice and provides some flexibility. The structure of the class having homework and quizzes make up 50% of the grade and also the reasonable difficulty of each helped reduce my stress somewhat in regards to this class.

Exams were a mixed bag. The midterm was reasonably doable, but I personally screwed up a simple concept by accident which was part of my downfall in terms of the grade I received. In addition, I think the grading may have been slightly harsher compared to quizzes because an answer to a proof that looked similar to one I provided on a quiz received slightly less credit. That said, I think the midterm was relatively fair. On the other hand, the final was absurdly difficult and the types of questions asked were vastly different from any of the homework and quiz questions. I walked out of the exam feeling more confused about the material than when I walked in. Even the more computational questions were difficult. I think to be prepared for the final, you would really need to go above and beyond in learning the material, reading up on the topics discussed further and really refining your proof-writing abilities. I didn't get an amazing grade on it, but I ultimately passed the class so I can't complain.

Would I recommend this class? Assuming you need to take it for your major, it depends. I do think there are probably better professors out there, but the grading in Professor Huang's made it doable overall and she's certainly better than a lot of the other professors who teach this class. If this class fits best in your schedule and/or the other professors are not great then sure, take this class. If another excellent professor is teaching this class during the same quarter, they might be a safer option. Do I regret having her though? No I don't, I think her class was overall fair, except the final.

I think Prof. Huang is a really nice person who genuinely tries her best to help students. I never went to office hours and I wish I had but I heard that people who did got a lot out of it. She's also good at clarifying things if you ask her questions during/after lecture. Her lecture style is kind of boring (she just writes notes on her iPad and you copy them down) and I found it difficult to apply what we learned in lecture to homework problems. Problem sets are very easy and short (3 problems per week) and weekly quizzes were usually one of the homework problems, which was a blessing. That being said, I think you should be doing way more than the assigned homework in order to understand the concepts, and she provides a list of suggested practice problems that are in the textbook. My TA was June Bahr and I recommend her! She seemed very passionate about the subject and was great at clarifying concepts that we learned in lecture and explaining homework problems. I really struggled in this class because I didn't really try to do extra problems or study outside of class until it was too late and ended up doing really poorly on both exams as a result, but Prof. Huang curves very generously so I was able to get a B- instead of the C/D/F I thought I would get. If you're a math major there's no avoiding this class, but if this isn't required for you I have no idea why you would take it unless you're really passionate about the subject.

Avoid this professor. I have nothing good to say about her.

Huang is one of the worst lecturers I’ve had in my 3 years at UCLA. She often discusses topics without motivating them, making it tremendously difficult to follow along.

She is also one of the least helpful people I have met in general. She is short spoken and, according to one of my friends who has taken another class with her, will intentionally withhold information from you if she does not like you. I also once asked her a question during an exam, and she took the extra time and effort to utter a belittling and rude remark about my capabilities.

The midterm was very similar to the homework assignments and relatively manageable. On the other hand, I felt like doing well on the final relied too much on keeping up with tedious algebra and remembering easily forgettable facts from pre-requisites.

I would really recommend taking this class with another professor if you get the opportunity.

Ta is even better than professor...

Do not be scared by other nasty negative reviews because they are old and Prof. Huang has improved at lot. She posts all her notes online every week, which is pretty great for review and catchup. She gives about 15 questions per week for homeweek, which is very managable. Tests are not challenging at all, and are straight from the homework and examples from class notes. The final is slightly more difficult than the midterm though (only one midterm for this class). Not the best math class you can take but I will definitely recommend.

Look, her English may not be the best, but after reading the 33A reviews, it seems to me that they just seemed to dismiss her help immediately. Professor Huang is an extremely helpful person in office hours, and our TAs are also great resources. I was at times frustrated, but she certainly did put an effort in improving her lecturing. For the reviews of her on 33A: If you ridicule her for her thicker Chinese accent, chances are you are just trying to find excuses as to why you cannot grasp simple concepts in linear algebra. Grow up and have some empathy. In my Math 115A class, if we asked questions relevant to the material, it'd often clear up her explanations, as well as our own understanding of concepts. Don't dismiss Professor Huang just yet, as she has become a much clearer lecturer and is a very, very, very fair professor.

I don't know why people in her 33A class kept complaining since 33A is all about computations, which is much easier than 115A. It’s true that she is not a good lecturer since it is the first year for her. She does not explain all the concepts and proves very well in class. Sometimes her homework requires us to do something that is not taught in class.
Everyone is complaining here, but I will say you can never expect your teacher to teach you and make you understand everything in class. You have to put your effort into it, try to figure out the things you do not understand instead of complaining that your teacher didn’t tell you. If you did not get good grades simply because you did not work hard enough, then stop complaining.
Finally, someone also attacks her Chinese accent. For those people, I have two words for you: 垃圾。
