took his 104A earlier so take this 104B again. getting a good grade is not easy when your TA is tough, but prof himself is not bad. hw is reasonable. if u skip his class, dont skip the review session. the grading policy is so nice. the "drop the lower mid score" literally saves my life. //will write another comment when i finish his 104c.

This professor is extremely straight-forward. The homework for his 104B class wasn't so bad either, especially if you work with your peers. His exams are awesome. He has a review lecture and goes over ALL possible questions he could ask you in the exam and goes over how to do them in detail. It seems pretty counter-intuitive, but I learned a lot.

legendary. Guaranteed A if you go to lectures and put in a little effort.

Prof Xu Yang is very nice and patient. He has review sessions that help us prepare for mid & final, which is SUPER helpful. drop the lowest for one of the hw & one of the mid.

Literally just used another professor's lecture slides and notes.

Very heavy accent and does NOT care about his students. Just keep talking and talking and assume everyone knows what he talks about.

Professor Yang communicates with the students often with emails, his lectures were straight-forward and I felt like I had a deep understanding on the content, and the exams are challenging. I strongly recommend for Math 3B.

Did not even create his own lectures, used another teacher's lectures from the previous quarter - everything was asynchronous. Quizzes were 5 questions and the lowest one is dropped. You will definitely need to study extra for this class if you want a good grade in it.

Very disorganized lectures. Bad handwriting and difficult to understand. Lectures consist of him doing examples while providing little to no explanation. Do NOT recommend.

wasn't attentive to student needs :(

Super disorganized, hard to understand his speech or handwriting, no response to emails, posts hundreds of hw problems but doesn't say which are important, midterms and final consists of some stuff we don't spend any time on. Didn't show up to any of his exams which all had grading errors, Yang is intelligent and a nice guy, but bad at teaching.

Extremely unorganized from the start. He writes so messily on a tablet and his explanations are so bland. He changed his grading scale so many times throughout the quarter. He never showed up to exams because they had mistakes on them. Some things on the midterms were never covered in class. Some people aren't meant to teach and he is one of them.

He is a nice guy who is good at explaning concepts and giving examples. He writes his notes on the board and does not post anything on gauchospace. He requires us to register ourselves on wileyplus which costs me $120 for homework.

Professor Yang has been my only math professor at UCSB that I have consistently been able to follow, every lecture. He has a bit of an accent but, overall, his lectures are extremely clear and helpful. They apply directly to the homework and tests, and it is easy to succeed if you show up to every class.

Pretty hard to understand during lectures and re-writes book examples for lectures. Midterm was OK; however, the final was very difficult. Try to avoid him as he is a hard grader with no curves.

Midterm was easy, straight from the homework but the final was very hard. Section isn't mandatory but TA Peter is very nice and quizzes are easy so make sure to go for an easy full 10%. Weekly homework due on Wiley ($97) just go to Math Lab and ask for help or google the question. Btw, no curve.

Homework assignments are on wileyplus. Exams are tough. He said he would make the final easier than the midterm, but I'm unsure what his definition of easy is.

Midterm was trivial but heed this guy's warning about the final because it was downright insane. First final I've had where EVERYONE stayed the full 3 hrs. Horrific accent, no lie. And writes small so try to nab a seat in the front. Lectures are also very dry, but hes a nice dude.

Professor Yang was very clear in his explanations. Hes also very cute like 9/10 (^_^;) and he has neat handwriting. I believe that I could learn a lot of differential equations from him.

Thick accent, easy midterm, take CLAS instead of going to class. CLAS guy (Tyler) is super helpful.

His class is really easy, but he offers little to no help with homework and preparation for tests. Utilize CLAS, section, and Math Lab as much as possible, and it's an easy A.

Yang is really an easy going professor. The first midterm was super easy, he says the final is going to be harder but I am not too worried. We moved pretty slow and he even didn't have time to finish some topics. The homework is on wiley and it sucks. The textbook also sucks. Yang also has a thick accent that is hard to understand.
