MATH 2310

Professor Qi is a very kind and helpful professor who truly cares for the success and wellbeing of his students. While it can be stressful to have a midterm worth 30 percent of your grade and a final worth 40, he is very forgiving on grading these and gives problems that pretty much match exactly what you do in the homework and quizzes. At the end, our class had a curve such that an 85 was an A-, a 75- was a B- and so on, which was nice. If you forget to turn in homework once he usually takes it late anyways if you go to his office. Lowest quiz is dropped and for homework sets, he only takes off 1 point out of 100 for each wrong question (yes, that means if there's 20 questions and you show your work you'll at least get an 80 on it). I HIGHLY recommend reading the textbook thoroughly and doing extra problems from the same sections he assigns from. It's a short book, but it can basically teach you the material itself (what's covered in class doesn't really deviate from what's in the assigned reading at all).

Professor Qi is very calm and kind, and is great at teaching concepts through relatable metaphors. When you learn things like double and triple integrals, be sure to pay attention to the "bread loaf" method, since it's both fun and engaging. Professor Qi was also very helpful in office hours, and even if his regular hours don't work with your schedule, you can coordinate with him on other times. Ask him any question about the content and he will answer the best he can without being judgmental--he always welcomes questions, big or small. Weekly homework sets can be challenging but are very manageable if you go to office hours. The lowest two homework sets and quizzes are dropped. I am really glad I took Calc 3 with Professor Qi, and I highly recommend you take this class with him too if you can.

I stressed about this class more than I should have. At the beginning of the semester it seemed like it was going to be rough, but as it got going, Qi proved to be a pretty good professor. To be successful in this class, you definitely have to put effort outside of class. I found myself watching a lot of youtube to understand concepts better. The weekly homework isn't that bad, but the weekly quizzes in the discussion section are hard to prepare for and can be annoying. That being said, unless you don't answer the questions at all, you'll be fine on the quizzes. The TA for the class was not great. He wasn't great at answering questions or explaining concepts, but there were a couple important things that I gained from the discussion section. The final wasn't terrible if you understand the concepts in the course (just don't make silly mistakes!), and I got an A in the class with an 85 on the final. I got a 78 on the midterm, but luckily he offered a kind of dutch knockout system where the final was either worth 40% or 70%. Overall the class is fine, but I don't think it invigorates a passion for math.

This course was very insightful into the world of multivariable calculus and its applications.
There was weekly HW assignments (WebAssign, ranged from 12-18 questions) and weekly quizzes in the discussion section (2 questions). The weekly HW assignments took about, on average, 3 hours to complete, and were not so difficult. Lectures were informative, but extra studying outside of class is necessary (especially for some of the geometry and visualizations).
The professor was understanding and clarified doubts regularly, but sometimes the class would be a little too theoretical and there would be many examples of special cases of concepts rather than general cases.
The TA was new this year and he was helpful in connecting concepts to applications (in physics especially). He was also a generous grader and open to any of our doubts.
midterm was difficult and slightly unexpected, final wasn't so bad and expected
I would recommend this class if you're interested in calculus past calc 2, CS, physics, math, or finance. #tCFfall22

Was a nice person but a really bad teacher. Would overcomplicate any question no matter how simple and was generally unhelpful and lacked awareness of students' understanding. Exams were much harder then any content previously seen. Whole class did so badly on the midterms that he had to offer previously unplanned test corrections. Also serious disconnect from TA and teacher as the TA did not attend the classes but made our quizzes.

I cannot recommend taking this class with You Qi enough!

I am a BACS major, and I wanted to take more math to be closer to the degree in the e-school. But whether you are taking this class as a math major/minor or for simply rounding out your calculus understanding, I cannot recommend it enough. This class is a good bridge between more computational math and higher-level mathematics. You Qi focuses not just on computations but on actual understanding. He goes over proofs and has students do sort of pseudo-proofs on a few of the homework assignments.

This class takes a lot of time and is definitely hard, but it is ultimately very rewarding, and that is just the nature of the course. I recommend taking You Qi's advice and reading the sections of the book alongside the lectures. There is so much material, so sometimes the book is needed to supplement what is gone over in class. Also, don't feel bad if you feel lost sometimes in lecture. It does go really fast. But, office hours and the book make it very doable. And by the end, you will see how far you've come.

As for the tests, assessments in the course are quizzes, a midterm, and a final. Quizzes can be somewhat hard, and you really do only have ten minutes so reviewing the content from the week before taking them is helpful. But, they are ultimately fair and some are dropped. As for exams, these were more than fair. If you know the content going in, you will be fine. And You Qi let us have a cheat sheet as memorization is not the goal of the course. Further, I know in previous semesters when there were issues with exam difficulty, You Qi corrected them fairly. He is kind and generous.

Definitely take this course and take it with You Qi! Good luck on your math journey.
