Mr. Ye assigns a good amount of homework, but he gives a lot of it in a short period of time. If I were you, make sure to go to section and make a study group. Honestly, I don't think I would have passed without it. Also, he lets you have a notecard for the midterms and final, but no calculator is allowed. Good luck!

It seems that he doesn't prepare for his lectures. He doesn't explain concepts clearly, and usually makes simple things confusing. The exams are hard because it is always "impossible to assign new homework due to some system trouble". The worst teacher I've ever had.

His lectures were confusing and very unorganized. I didn't get anything out of them and basically taught myself by doing the book problems at the end of the chapters. They help a lot for the tests. Make sure you use CLAS because it is a lifesaver. I wouldn't take a class with him again but it is doable if you work hard and have no other choice.

Although Professor Ye's lectures weren't the most clear or organized, he seems to care about his students' success. He made it a point to ask us how many review days we wanted before the final, and (notoriously) uploaded an outline of the final to review on his site. Homework was not comprehensive, but the exams were easy. Go to section!!!

Lectures are boring and make the subject more confusing. He has a strong accent. The homework is not similar to the tests. On tests, if you get the correct answer but your explanation isn't "correct enough" you won't get full credit. I would not take a class with him again. If there's no other option, then sign up for CLAS. It saved me.

The class itself is hard, but his midterm exam consisted of 20 extra credit points wich was extremely generous. He understood it was an intense class and for the final he asked the class what method (in classtake home) would work best for us. HW is tough but nothing like the Exams, they will put you at an advantage but READ THE TEXTBOOK!

Ye is really good at teaching you the material, very insightful if your math sucks, but he can write on that chalkboard at unreal speed, and it can be pretty hard to get everything in your notes. Homework is really fair, final was unreasonably tough. If you get stuck on an exam problems, try all the math tricks you know until you can solve it.

Let me begin by saying that I think Professor Ye is a good lecturer. I came to class every week and got a lot out of them. That being said, nothing that I got out of lecture was applicable to the tests. A question on the midterm was poorly worded, costing me 20 points and the final consisted of all near impossible questions, nothing like in lecture

Professor Ye was very clear, he often took time to turn around and explain concepts in depth instead of busily writing on the board all lecture. Tests were very fair, Webwork due weekly. I am a math major and I thought he was very knowledgable about the subject and fair with his teaching. I had lecture at 8am but rarely missed. Used the book A LOT.

Course material is straight forward. Always presents example proofs and often shows different ones than from the textbook to let you see the multiple ways to approach things. Lecture is sometimes silly when he spends the whole time on one big proof but typically the concept demonstrated is essential. Tests on the basics, nothing tricky.

Professor Ye was usually unprepared for lecture. He was very unclear with his teaching and although he is a good mathematician, he struggle to communicate concepts to the class. Most people stopped showing up. He also didn't use Gauchospace so there is no way of knowing your grade at any given point.

He is THE worst professor of all time. He knows a lot about math but has absolutely no idea how to teach. The 2 midterms were easy but the final was a nightmare. Only about 40 kids showed regularly to a class of over 250. He is super unclear, goes off on class-long tangents, and doesn't communicate to the students at all. No way to know your grade

Actually I think professor Ye is a really nice guy, he is not give us really hard time on homeworks or midterms and finals. all materials he tested us were the things he taught in classes. He is really serious about teaching and willing to answer all the question(you just have to ask!!!!)

He's a terrible professor He has office hour but seldom there at office. The tests are out of wall. He cancelled our weekly homework because there is no grader. Then he adds the percentage of homework to the final. He sometimes speaks Chinese in class. He always skip the questions that asked in class even makes me think he doesn't know the answer.

The worst teacher I have ever had! AVOID AT ALL COSTS! He has made it clear he prioritizes his research and grad work over our course. Spends as little time on our class as possible. We were unable to get a grader for our homework and he refuses to provide solutions. No way of knowing where you stand in the class. TERRIBLE PROFESSOR!!

Another horrible UCSB math professor. Very difficult to understand with accent and weird logical progressions of his derivations. Section was a joke, TA useless if he even showed up. Homework moderate, CLAS is where I really learned. I was pretty mad because went into final with a solid A and came out with a C, someone ran out in frustration...

i would try to take another prof if you can. he is difficult to understand and often pays no attn to the class to see if they are following. you really have to pay extreme attn and ask questions and tests are insanely hard. he curves favorably though

just completely bombed that final. it was even harder than the midterm. hw is webwork and not too bad... exams are super difficult versions of the relatively easy concepts covered in the class. he intentionally makes the exams longer than is possible because he curves.

Only thing he does in class are trivial examples and examples from book. Pray you don't have him.

Bad just plain Bad teacher....independent study and/or CLAS with Jesse/Alex is a must. uses problems/exams from previous years so use google.. allowed any size notecard on final so I used a poster: like half the test was on my notecard lol

He is one of the worst teachers at UCSB. He is very incomprehensible....have the time I am trying to figure what he is saying rather than actually comprehending the material. The midterm is pretty easy, but he made the final impossible. Everyone was there the whole three hours and even the TA's said it was one of the worst finals they had seen.

His lectures can range from pretty good to not very helpful at all, but I recommend going to his lectures anyway as some of the things he does in lecture are likely to end up on his tests. Gave 25% worth of extra credit points on the midterm. Really loves critical point problems. Final was harder but curves the class.

Vague prof who jumps around in the book, go to 'pauls math notes' on the internet, that website saved me in the class, the book and the prof imo were not too helpful

Horrible, horrible lectures. Completely mislead the entire class this quarter on the material that would be covered on the final. Had an amazingly easy midterm. Class average was a 90/100. Final was insanely difficult as the material mainly consisted of the last two weeks of class that was very weakly covered. Should have spentmore time with topics
