MATH104B . 2 Years Ago

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.

MATH104B . 7 Years Ago

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.

MATH4B . 9 Years Ago

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.

MATH4B . 10 Years Ago

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.

MATH4B . 10 Years Ago

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.

MATH4B . 11 Years Ago

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.
