Chi-Yun Hsu is not just my math professor; she is my role model. She teaches everything very intuitively and her tests aren't too hard as long as you keep up with homework. You don't even need to attend office hours or anything to get an A. She's a really good professor, and she makes a new worksheet for every class, which makes for easy revision at the end of the year. I LOVE HSU <3
Prof. Hsu is a really good teacher and individual. She focuses a lot on getting the mathematical concepts across to her students and wants them to really understand the concepts instead of just applying them blindly. She puts a great deal of efforts in making sure her students understand her stuffs and is very helpful. She really cares for her student. Her notes are really useful for the tests although that does not make the tests any easier. Overall, she’s a really good teacher and definitely will pick her again to teach Maths in the future if possible.
I love Dr. Hsu, but here class is unreasonably difficult. I genuinely enjoyed going to her class, even though I dislike math and it was an 8 AM class. She is really nice, sweet, and helpful. Sometimes, she's funny too. The homework is harder than the class, but that helps me learn. The only problem with this class is the fact that the tests are really hard and she doesn't curve. Our first midterm had an 82 average, which was great. But the final and midterm 2 were around 72%, I don't remember exactly, and she didn't curve the tests. The final was by far the hardest test I've ever taken, and without the curve I went from having a B+ in the class before the final to a C+. If you really want to learn take Dr. Hsu, if math isn't your strong suit and you just care about the grade take an easier professor.
Hsu is a great professor and a nice person, and she really cares about her students. Her lectures are organized, and she gives out worksheets for lectures, which are really helpful. She is good at explaining concepts and theorem clearly. Her tests are not so hard. Even though there are a couple of tricky problems in tests, she does not put a large amount of points on them. Therefore those tricky problems will not prevent people from getting an A as long as they do well in those normal problems. Generally speaking, Prof. Hsu is the kind of professor that I will choose to take further courses with.
Professor Hsu is one of the most brilliant math professors I have ever been taught by. Her lectures are incredibly organized, and she gives out these comprehensive sheets every class that effectively summarizes the topic covered in that class. Her homework questions are very simple to do if one revises their class notes and reads that section from the textbook. The homework also helps you gain a better grasp of the different types of sums that can be asked from that section. Her midterms had pretty standard math sums of similar difficulty to that of the homework. She, however, asks a bunch of True or False questions in her midterm and final which are very technical in nature and are worth a lot of points (so remember to learn your theorems and understand your concepts well). Her midterms are definitely lengthy but are pretty possible to finish as long as you don't get stuck on something for too long. Her final, however, was considerably much easier and much more lenient time-wise. Her office hours are extremely helpful only if you have questions that need to be answered and she is very helpful in answering doubts and clearing concepts. She is very approachable and makes an effort to remember your names.
Tip: Something that really helped me with the homework for this class is forming an intimate study group of 2 or more people with whom you discuss the homework on Thursday (as every homework assignment is due on Friday). It helps ensure that you have all the right answers if you were not able to make it to office hours and ensures you finish the homework a day early instead of rushing to finish it later. Homework is worth a good portion of your grade, and it is very easy to mess up so be careful.
Even though she teaches the subject well, I wouldn’t say her style is for everyone. She focuses on the conceptual aspect of math and tries to explain where the formulas come from. She expects students to be somewhat capable of intuitively understanding math. Her exams and midterms are generally according to this too. The problems are designed to evaluate wether or not you really understand the topic and that you don’t just plug numbers into a formula. She always asks true/false questions aimed to test students’ conceptual understanding which are worth around 12-16 points and generally tricky and not that easy. So if you really enjoy math and like to understand it on a deeper level I really recommend taking her class. However as someone who gets stressed out by math and would rather just get it over with, I found her class challenging. Personally, I didn’t have a strong math foundation and I always hated math so if you are like me and just have to take 31A for your major, just pick a more chill professor. But even though this class was hard for me, I really improved my mathematical knowledge a lot and I was really surprised to see how much I learned in 10 weeks. Of course the pace is quite fast and she assigns 3 homework assignments each week (uploads them after each lecture) so you have to stay on top of your work which is actually not a bad thing but I would say the workload was a bit much. The homework is collected every week (you can also upload it to CCLE you don’t need to turn it in physically) and some “grader” grades it (4 questions are chosen randomly and graded, 3 points each, and 3 more points for completion, the average of your homework grades make up 15% of your final grade) There are two midterms and a final exam. Depending on your scores the calculation of your final grade is either 35% midterm1, 35% midterm2, 35% final 15%hw or 35% midterm that you scored higher (lower one gets dropped) 50% final 15% hw. She doesn’t curve her exams and she tries to keep the class average around 70). Below 70 fails. Lastly, about Prof, Hsu, she really cares about students and she tries hard to explain well. She is very helpful in her office hours and solves homework questions so I recommend going there if you ever get stuck. She puts the effort to remember the names of the students who go to office hours and she is a sweet person. She also cares a lot about student feedback and tries to take the surveys she makes students fill out after the first midterm into account. For example she said people told that she skipped some steps in problem solving (which she didn’t, even I could understand how she did the calculations with my bad math foundation) and she immediately changed the way she solved questions she detailed the explanations. On the first midterm T/F questions were around. 30 points and people complained about that so on the final and the second midterm they were 16 and 12. Overall, Prof, Hsu is a nice professor and she teaches well (she was out of town for a week and we got other 31A profs for substitutes and she was way better and clear than both them), I recommend her if you like and get math, or need good explanations and extra help.
I took this class fall quarter of my freshman year. It was 4 days a week at 8 am, a freaking nightmare. Anyway, Dr. Hsu was a good professor and I understood the material taught in class. However, maybe that was due to the fact that I had already covered most of the topics of this course in high school with top grades, but couldn't transfer credits so couldn't skip the class (I am international). Her midterms weren't too hard, but very long. You have to go very fast or you won't finish them. Instead, I had plenty of time on the final. Also, the problems on the tests were usually not the hardest kinds that we did in class. For example, for volumes of revolution, instead of having area between curves rotated around a random axis y or x = k, we only had to compute the volume of the sphere around whatever axis we wanted. That was very nice. Homework is not heavy, but sometimes she assigns super hard problems that not even the TAs can do on the spot. To solve those, go to office hours, they are super helpful and she gives out homework solutions. Homework is graded, so that's basically free points. no participation grade for this class. The TA Erza Thompson is super boring. Overall, my experience with this professor was good, also because of my grade. Consequently, I chose her again for Math 31B.
Dr. Hsu is a great teacher. She knows her things and teaches well and is extremely helpful. She provides Assignments in each and every Class which has the Theory and Questions on the Topic she will be teaching in that specific Class. Homework Questions are easy and doable. However, neither of them will prepare you for her Exams especially the True and False Questions which have an unnecessarily high percentage of marks. For Math 31A (Fall 2019), she tested us on Sections 6.3 and 6.4 which were not tested in other Math 31A Classes which made studying and the Exam more difficult. If you are a person who can do well or even just sail through the Exams, I will highly recommend Dr. Hsu.
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 :)
