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!!

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.

31B is a difficult course overall I think. Prof Hsu is very kind and really does do her best at explaining things, especially when asked directly. However, I was not a super big fan of her teaching style. She tends to teach very conceptually and rarely did we have time to go over more difficult examples like the ones on the hw. That being said, tests were very fair, especially with the 24 hour format. She's a solid professor, but her style is not really my cup of tea.

Math 31B with Professor Hsu was a walk in the park. The professor was very engaging and understanding. During COVID, tests were 24 hours, open note, open resources. Professor Hsu really cared about students' feedback and made sure that everyone was getting the material. 10/10 would recommend.

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.

Hsu is a great professor! I think that sometimes people get frustrated with math classes because they expect to understand every little concept just by watching lectures. But as she explained, her job is to give you the tools to be able to do the homework and to start challenging yourself with more complicated problems after the lecture. She isn't always the greatest at explaining/clarifying things, but she makes an honest effort. Her lectures are clear and engaging and she is very personable. If you have any issues with how she teaches, she is extremely receptive to criticism and is fast to make changes. In order to succeed in this class, make sure you understand how to do the assigned textbook problems inside and out.

Overall, she's a great professor to take 31B with!

This class ended up being better than I thought it would be, and it felt easier than 31A in terms of content. I think the pace is pretty reasonable, but it does seem like a lot of material. Professor Hsu is not the best lecturer because sometimes she is not very clear, so the textbook was useful. The open note aspect of the tests was extremely helpful. If you are prepared to put in the time and effort, then you should do reasonably well.

A lot of people here liked Hsu but I personally didn't have a great experience. A lot of it is my own fault. I got behind on homework and started paying less attention in lecture, and though I got an A- on the first midterm, I got a D+ on the second midterm because of my own mistakes. I took this as a learning opportunity and managed a 98 on the final, so that I ended up with an A- in the class.
Hsu's lectures can be pretty unclear and unengaging, and at times it was difficult to follow what was going on. Reading the sections of the textbook really helped me, as did watching videos on topics I was struggling on on Youtube. There were some things that made zero sense when Hsu explained it, that made perfect sense when I watched a 7 minute Youtube video.
If you manage your time and stay on track with the homework and readings, and DON'T do what I did, you should be okay. Hsu isn't bad, she's just not great (especially compared to Conley who I had in 31A)

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 ********** if ur interested :)
