She's a great teacher. Only criticism is that the exams are pretty difficult. Prepare for true/false. I know.

the tests were hard, but using the textbook helped as i could do problems for extra practice. im selling the rogawski's 4th edition single variable calculus textbook for $65! msg me at 3473398165 if ur interested :)

Overall, I enjoyed this class and had a relatively easy time. Sometimes the lectures would get a bit confusing but Hsu was always willing to go over any problems that confused you. I do genuinely believe that Hsu wants students to do well and she’ll make sure to address any questions students have. If you’re ever lost during lecture I highly recommend going over the textbook examples- they helped a lot.
The first midterm was really easy and straightforward. The second midterm was slightly harder but still doable. In my opinion, the final was harder than the first midterm but easier than the second. You can find examples similar to the exam questions in the textbook.

Professor Hsu was way better than my 31A professor, but even so, not the clearest. Lectures are BruinCast which is nice. She doesn't curve at all which is concerning. The only reason we all did well was because of the generous final grades due to COVID-19. Her policy for quizzes is nice. They do help raise grades and serve as a checkpoint of sorts throughout the quarter. The lowest grade is also dropped. From what I've heard from other 31B students, she is the best professor to take for this class.

Fantastic class! It's fast paced-- you'll certainly learn a lot! Professor Hsu is super helpful, and she seems to really care about her students. Definitely do, and study, all the homework and lecture problems-- you won't regret it.

Hsu was an amazing professor, and I highly recommend her to anyone who really wants to understand why something works!
She was super sweet and understanding and actively listens to feedback. Some people were saying that her homework was too much (I agreed), so she actually removed some questions and kept them as optional ungraded practice. She doesn't curve down, but I don't think she curves up either. I asked a ton of silly questions during class, and she took the time to answer all of them (either in class or in office hours). She's super knowledgable and really knows her stuff!
She's super accommodating as well. My power went out, so I asked for a one day extension, and I think she granted a week extension instead. I straight up forgot to hand in an entire quiz, and she didn't count that against me in my grade. Plus, I was being silly and forgot an entire page in my homework when submitting (export error), and she accepted the last page late cuz my first two pages proved I did it. Plus, some people ended up cheating on the midterm, and she did not penalize anyone who came forward, which again felt more than fair.
This may sound slightly nerd-ish, but her tests were also super fun and fair! I felt like everything on the exams were more than fair game, but they were still decently challenging, like a good puzzle. For online schooling, her tests are the perfect thing to just put on some music and get cozy doing them. If you do all of (or a majority of) the homework, attend her lectures, and skim the textbook, the tests should be a breeze (but a fun breeze!).
I highly recommend her as a prof!!

I took 31A and 31B with professor Hsu and I believe she is a great professor. Her lectures are clear and usually pretty much everything in the test is covered in lectures / hw (maybe one question per test is a little harder). She's super helpful with students (OH, emails, piazza etc.). She also gives extra credit, 1% overall, which is a lot on a not curved class. In fact, at least for 31A,B she assigns grades on the standard UCLA scale: A+ 97.5, A 93%, A- 90 etc. However, if the class doesn't perform well, she finds way to bring the grades up (ex. with extra credit on the final to make up for a midterm with a low mean). Her quizzes are also fair and a pretty easy way to bump up your grade (they were hw problems). I didn't really like TA Erza.

Took this class during covid-19 pandemic. I love professor Hsu, she was the most helpful and accommodating professor I had all winter quarter. She will answer any question you ask her, and will explain it to you until you understand. None of her lectures or discussions were mandatory, she records all of them so you can access the lectures from whichever timezone you're studying from. Exams all have 24 hour windows and are open book. I'm hopeless when it comes to math, I've always hated the class and the only reason I'm taking math 31b is because it's a prerequisite for higher econs classes. Please, do yourself a favor and take all your math classes with prof Hsu. She's a godsend.

It can be confusing listening to Professor Hsu's lectures, but when you go read the corresponding sections in the textbook afterwards you will find things start clicking. The content is manageable if you find a balance between her lectures and the textbook descriptions. Overall, I enjoyed the class and Professor Hsu was very helpful and kind.

Prof Hsu is hands-down my favorite professor this quarter. I switched from a 2PM lecture to this 8AM just for her teaching. She gives out worksheets every lecture going through the concepts- don't even bother taking notes, as filling in the worksheet while she lectures is super helpful. The other reviews are definitely correct: while we had averages in the low 70s for both the second midterm and the final, she didn't curve, though it says in the syllabus that she may lower the cutoffs for the grades. Furthermore, her exams do contain True and False questions that are around 12-20% of the grade. Personally, I felt as long as you stayed on top of the theorems and knew how to apply them, they weren't that hard.

There was two grading schemes: one with 15% for HW, 25% for each midterm, and 35% for the final. The other was 15% for HW, 35% the max of the two midterms, and 50% for the final.

She offers office hours twice a week, where she goes over hard homework problems, any questions, etc. I went every week and they were definitely super helpful. She definitely wants her students to succeed, and takes every measure to help them. She conducted her own mid-quarter (anonymous) evaluation, and she actually ended up utilizing the feedback (lowered percentage of T/F questions), which is more than I can say for some of the prof I took this quarter.

For exams and homework- she really emphasizes the importance of knowing how to solve things versus just getting the correct answer. Even if you run out of time on the exam, writing down your strategy will give you more points. That being said, if you guess or don't show sufficient work (I found this super arbitrary and unfair at some points) you will get docked.

All in all, I'm really happy with this class this quarter. It was definitely hard, but I recommend taking Prof Hsu if you can- you'll learn a ton.
