Wasn't the best professor at teaching but gave exams that were exactly as the practice test making it very easy. I appreciated the easy A but if you want to learn everything fully, might not be the best.
His practice exams are almost exactly like midterm/final except for one or two questions on them. Because of this I was fine with skipping lectures and then just reviewing the material that is on the practice exams. We were allowed front and back cheat sheets for exams and he didn't care what you put on them. It was an easy A if you practiced.
This professor is pretty nice and passionate. The exam is easy if you do the sample midterms carefully. I really recommend this.
Cool guy
Heavy accent, boo hoo get over it. He is not that bad, especially when compared to other math professors here. The main ones complaining abt yan prolly are that one econ major friend you have who parties every weekend, and even they got a good grade prolly. Just study the study guide and do the hw, you will be fine.
The exams are easy,and the homework load is very low. He is a very good teacher!
Best teacher ever, 100% recommend if you are taking Math 3B, grading is very clear, quiz is reasonable. Professor Yan yyds.
This professor is very hard to understand and frequently solves problems wrong/skips over steps when solving problems (as if assuming you know them already). Barely gained anything from lectures. However, the study guides for the midterm and final were basically identical to the exams. Basically gives you the A if you can teach yourself.
Beware of Zetian Yan. His lectures are impossible to follow. He speaks far too quick, he doesn't explain his process or the material. He simply solves the problem and expects you to know what he did. When a question is asked, he doesn't answer it clearly, rather leaves me more confused. Lots of homework, but the homework is better than the lecture.
This professor does not know how to teach and is very hard to understand. He solves problems, but is typically unsure if he is doing them right and makes a lot of errors. However, if you just want to pass, it is very easy since he gives study guides that are nearly identical to exams. Self teaching is required in this class.
GOAT lmaooo, but don't take him if you actually want to learn abt calc 2
Lectures are super hard to follow and no slides/structure, just solving equations and problems with little explanation. He is not super receptive to questions either, ended up teaching material to myself and never going to lecture. Homework is pretty reasonable though and midterm was the same as a practice midterm he gave to study beforehand.
Yap session
Yan is nigh impossible to understand due to his heavy accent and mumbling. He teaches easy topics in a confusing way; I can't imagine how hard it would be to follow his lecture later in the course. The homework on Canvas is not at all what's being taught in lecture (it's also much harder). I've since switched to a new professor and am much happier.
Prof Yan is joining us temporarily(?) from Penn. I found him extremely hard to understand. The flow and structure of his lectures added difficultly on top of that. Questions were not laid out well. I dropped the class because it was only going to get worse. He is bilingual, so if Mandarin is better for you, this may be helpful for office hours.
Excellent professor! The lecture is clear and the grading is easy.
Take all your classes with Zetian he is SO easy!
He is kind and a very easy grader. Take the class for an easy elective.
Honestly the class was a joke, we just used Rudin but the lectures were just him reading the theorems and telling us to go over the proofs on our own time. The homework was super easy and he gave up part way through the quarter and turned this into a 6A class. It was super easy but you won't be learning anything from any of his classes.
Dude might be a genius, but very dismissive and overall one of the least professional professors I have ever experienced. Class was easy enough but I will never take one of his classes again.
Don't take this course. The professor have an accent so it is hard to understand.
I'm absolutely amazed how someone can say so much yet explain so little. Hes smart af but the lectures are all over the place. If you want a solid foundation in this class then prepare to self study.
Super easy, online everything, only learned because of CLAS. I tried going to his lectures but honestly I could not understand him much so I gave up on them pretty quickly (and he would use a chalkboard really far away so you couldn't see what he was even talking about). Easy A, if you want to learn, self study or take the class with another prof.
2 online midterms and online final. Lectures were directly out of the textbook (literally had it up on the projector) but there was no clear pace/was all over the place. Stopped going to lectures the last few weeks because those 8ams were BRUTAL and wasn't gaining anything. Take for an easy A, go to CLAS if you actually want to learn.
