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

Ye does not connect well with students. His class notes are useful and he is understandable, but his homework and tests are generally harder than what he personally presents. CLAS definitely recommended.

The first time I had him in 3C (i think) he was very hard to understand and i retook the class... but after having him again in 5b i realized you should just read what he writes instead of listening to his jibberish... tests are easy (THANK GOD!) though lots of hw.

Horrible professor!!! You can't understand anything he talks about in class and his language in totally different from normal language. He gave partial credit for his midterm but for his final he changed his mind and didn't give partial credit at all!! You definitely have to take CLAS for this class its will be the only way you understand the topic

Ye does not connect very well with students - I learned far more from CLAS and the TA than I ever did from lecture. Assigns TONS of homework, often too much to finish (and its only worth 10% of your grade). While he does have an accent, his English is perfectly understandble. Tests arent TOO terrible, but midterm & final are 30 & 60% of your grade

Great mathematician, bad educator. Does not speak in language of students, definitely does go on tangents that are irrelevant to class material.

With CLAS, this class was a breeze, his tests were fair and non-trivial. Do the homework to understand the subject and you are on track to getting a good grade in the class.

Dr. Ye is extremely bright and seems to be good at problem solving however uses a high degree of mathematical sophistication in his proofs which leaves many lost. He is extremely lazy(never collected homework cause he didn't want to grade) and is unapproachable outside of class however very polite. Only gave 15 min of office hours each day.

I thought previous comments about Ye were somewhat unjustified, or maybe he's changed his ways. Possibly he teaches 5B better than 34A. In any case, his tests were definitely not unreasonable, and he is enthusiastic about the material. Contrary to previous comments, his English is fine. Be warned that about 60% of your grade depends on the final.

The class shouldn't be as difficult as he makes it for some people. Cares less about the students than any other professor

He is not so bad as many wrote. He is honest and polite, at least. His feeling of students is poor, I agree. There were about five students in the class, but he spoke if he were in front of one hundred not bothering if students followed him.

hands down, rick ye is the worst teacher I have ever had.
