This class sucked. if you take 32b with yeong, you should not be taking other difficult stem classes. i was taking 33a with this class and it was too much for me. 33a was fine, but 32b was just unmanageable especially with the difficult midterms. and omg, the final was crazy.

prof yeong is not very helpful in her lectures as she pretty much just reads off the textbook material and uses the examples straight from the textbook. so basically you have to teach yourself all the material. don't go into this class expecting to understand any of the material from lecture. i took this class fall quarter 2023, and i think the prof was new, so i think that could be part of the reason why she was bad at teaching lol. i heard she's gotten better? like her tests are slightly more fair or resemble a few practice questions. but def take everything with a grain of salt. to be honest, it was also my fault for not putting enough time and effort into the class, but this class is just unmanageable with other mid-difficult level stem classes since it's hard conceptually. if you want to do well on her tests, you have to spend a lot of time practicing problems but not just the ones she gives you in lecture or on the hws, she made her test problems much harder so you would have to do practice for 32b questions on a more difficult level. so it's a pretty big time commitment in terms of studying.

Professor Yeong receives way too much hate. Sure, her lectures are a tad convoluted, but the homework is light work, the weekly worksheets are helpful, and the midterms are completely fair. Also, she has plenty of office hours and drops the lowest midterm score, which is more than I can say for other math professors here.

Feel nice Professor, ignore her past reviews, very accommodating and tests are not as bad as people say (mad cause bad); homework is not hard and easy to check via online sources.

Professor Yeong is a great professor! Her exams are very straight forward. The only suggestion I have is to go to her lecture and really do the practice exams. You will be fine.

Went into her class preparing for the worst since the quarter before was her first time teaching and she got absolutely blasted, but I did really well in her class.

Her lectures and slides were simple and nothing special (definitions, then theorems and formulas, then example problems), but I thought she was very clear and she was organized.

HW was fine, but as with most math classes, Quizlet Plus helps a lot. My discussion did a 15 min. review, then handed out a worksheet (or could be found on Canvas) that could be done there or turned in 24 hours later, but it wasn't graded on completeness, just evidence of some effort.

The two midterms were moderately challenging, but the final was nothing crazy or unexpected in my opinion. (Although, there was one part to a question that was more intuition than material knowledge. It was about partial derivatives and took me 40 mins. to finally get out of the 3 hour exam but I had the time and she gave a hint on where to start.) The final was my highest score of the three exams too. I thought her practice final was similar to what was one the actual final too.

Horrible lecturer; Insane Midterm 1. Squeezing 8 Mid to hard level questions in a 50-minute midterm is unreasonable and I don't think this is the right way to test the students' understandings. Do not take this class with her.

The content of this class is difficult; i've heard that it's the most challenging undergraduate math course offered at UCLA. With that said, Yeong does her best to make it as straightforward as possible. Take time to go over her notes and take advantage of TA office hours to truly understand the concepts. Once you understand what each formula actually means it makes the problems 1000x easier to compute. I had to watch the same youtube videos at least 10 times to understand concepts like greens'/stokes' theorem and the divergence theorem. It's so fulfilling when you do finally understand. You got this

Wern taught completely from the book and couldn't answer a lot of questions that when further than what was stated in the book answers. She gave practice midterms and worksheets which were fairly similar to the tests; however, the second midterm was a lot harder than the first. Her office hours were helpful in regards to homework solutions but she struggled to help those with conceptual gaps. The final was fair and her grading was generous, but when it came to overall grade in the class it was difficult to get an A because the range was adjusted for an A to be 95 and up.

Thank God for partial credit. I filled out about 25% of the questions on the second midterm (it was dropped since I did well on the first one) and got a 50%, so that goes to show you how generous they were with grading. Our average for the first midterm was around a 90%, second midterm around 70%, not sure about the final. The exams were not impossible. A lot of people say you have to learn/watch videos outside of the class, but I honestly think if you really understand the notes and a couple homework problems (exams were generally easier than the hard homework problems) you'll be just fine. The professor is a decent lecturer in my opinion and I actually liked the pacing and style of her lectures. The worst part about the class for me was the homework. Super long and hard.

Everyone seems to think Wern is an awful professor, but her class is really not that bad. There are ~10 homework problems per week, and seemed to be mostly graded for completion, with only a couple points (out of 100) docked for incorrect answers. Tests were generally pretty fair. Wern's lectures definitely lacked clarity, but the homework often made it a lot easier to understand the concepts we went over in class. Wern is not as bad a professor as she is made out to be, but I have definitely had better math professors at UCLA.
