Yukuns class is extremely old fashioned and lecture heavy. I don't think I've seen chalkboard lessons since elementary school. Aside from that, he's a nice guy just not a great teacher and his test content doesn't match his teaching style. Also, too many proofs

Yukun is a nice guy so I feel bad giving him a 1, but his teaching is so incredibly bad. He is obsessed with proving basic math, but then flies by the actual problems that are causing the class issues. On most occasions we have to beg him to finish the problem he was on so we can understand what he was doing. Avoid him if you can.

Although he was very passionate, his lectures were incredibly hard to follow. I ended up dropping the course and taking it with another professor the next semester, where things are completely different. Overall, very disappointing introduction to the math department at UW.

He sometimes does things in his own head that makes it hard for the students to learn. Sometimes rushes through the material and spends the majority of class deriving things instead of mixing in some example problems. Not the worst teacher I guess but I Just wish he spent more time doing more practice. Nice guy though

He's a poor lecturer but he's willing to help in any way possible as long as you just ask. A 1.7/5 is incredibly harsh for him, because he wants his students to learn first above all else, so he goes over proofs to help us understand why the stuff we learn works the way it does. Unfortunately, it seems many don't want to learn.

He's a hard guy to understand in class. He's not a very sympathetic grader either. I wouldn't recommend him as a teacher, I ended up learning everything in this course myself. He goes through the problems as if he were teaching a grad class, and most people didn't know what he was talking about in lecture.

His lectures aren't the best as he spends a lot of time deriving formulas instead of doing problems. However, you can tell he cares and is willing to help you. Great guy who wants you to do well, and will help you when you need it, but the lectures could be better. While he isn't a 5/5, 1.6/5 is VERY harsh for him.

It was hard to follow his lectures at times. Overall, I felt like lectures were helpful as long as you paid close attention. He was a very nice person, and I could tell he is very passionate about what he teaches. He was also very responsive to questions. He definitely does not deserve a 1.5/5 rating.

I want to preface this review by stating that he is without a doubt the worst teacher I have ever had. He is genuinely incompetent and comically bad at teaching. It is immensely difficult to understand him or his teaching style. Choosing him as a professor is essentially just choosing to self-study the course.

Really nice guy, I feel bad for giving him this rating, but his lectures are bad and his exams are even worse. The second midterm was infinitely harder than the practice exam despite him saying it was "easier", and it contained PROOFS, which is something we were told we wouldn't need to know. The average was a 58 for that midterm.

Yukun is a good person but I found him hard to understand and gained very little from his lectures.

Professor Yue teaches in a way that is impossible to learn from. He uses far-fetched concepts in his lecture that don't actually apply to the homework. He spends more time explaining why the concept can apply instead of giving example problems. Heavily suggest not taking

This is my second time taking Calc II (first was online in High School), and nothing is any clearer to me. Yukun's voice was always muffled and he has a very strong accent, I couldn't understand him. He loved proofs and would use class time doing them instead of practice problems to help us understand the material better. Do the practice exams!

Yukun is just not a good lecturer. The majority of the lecture is spent with him showing redundant properties of certain formulas and their applications. BLESS my TA she was actually so wonderful but legit I only did well because of my TA and insane amounts of studying before each exam. My one tip: do every previous exam on Canvas before each exam.

Professor is very nice but would go into derivations of equation rather than moving on to the next topic or showing examples of an important topic.

Nice guy, but teaches math so, so poorly. So many lectures were spent deriving formulas instead of demo problems. There was a time he spent 20 minutes proving that multiplication is commutative. Another time he full on said “you don't need to know this if you're not a math major”. So why are we doing it??? Did not help that my TA also sucked.

Just god awful

Very good at math and nice person, but has no idea to to teach. For example, spent the majority of one of the first lectures deriving a formula that would be on the formula sheet. Made relatively simple topics massively complicated by teaching methods nothing like those leaned before and going on tangents, even our TA didn't know what was going on.

Horrible lecturer, but he's a just chill guy that doesn't deserve a 1.6 rate my professor

Yukun is a good person but not a good professor. Lectures were not mandatory and honestly a waste of time. Lectures only consist of formulas and no applications. It is hard to understand and hear him sometimes. The TA's are good and help teach. Skipping lectures and reviewing on your own is a better use of time instead of the hour and 15 lecture.

He is an extremely difficult professor to understand. When he is working through problems and explaining things, it seems like it makes more sense in his head, but that doesn't always translate to the actual information received. Lectures are not helpful, if you have a good ta you'll be fine, but if you don't you REALLY have to self-study.

Refrains from doing examples during class and instead derives equations making everything very difficult to understand and hard to grasp when to use formulas. I have gone to every lecture and leave with a worse understanding than when I came in. There is a reason the average was a 56% on Midterm 2.

The professor did a very poor job explaining anything. I ended up not going to lecture and discussion after the first exam and did better on the next exams learning it by myself.

Is hard to understand, and even when you can understand it doesn't make much sense. Feels like he makes the class more like a graduate level class with proving everything, but never doing examples that help the students. Would not recommend.

If you can understand him, he's a pretty good professor. I found him easy to understand so I had a good experience with Yukun. He can still rush through things sometimes.
