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

As a student who does not necessarily excel in math, I felt like this class was great and kind to those in my position. The tests were difficult as they tested things we had learned but to a greater extent that made you think. The resources to get an A however, we definitely there and I feel if I retook this class with that mentality I could have truly excelled. Overall, she was a great professor and I would recommend even if you are nervous coming in.

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)

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.

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.

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!

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.

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.

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.

The professor's lectures can be confusing. She knows what she's talking about, but she goes through material quickly. I would suggest reading the textbook before lecture so you have an idea of what will be covered beforehand. Her exams were basically really hard computation problems.
