Number 1 Rule if you are taking his class: attend every lecture. all of the problems on the midterm/final were examples or proofs in lecture/homework. No outline for the course, no syllabus, heavy chinese accent but you get used to it. Everyone bombed the midterm, but you'll do well on the final if you just study his lecture problems/homework.

Nobody can understand what he is saying, and it's pretty clear to see that everything he's saying and writing is incomprehensive, especially when he writes with such a light marker and constantly erases the board that has material that he said we HAVE TO KNOW. The material taught was a joke, didn't prepare me for the midterm or final at all.

Proofs on lower division tests making up nearly 50% of the test grades. Not only that, he isn't teaching the material at all. Students don't learn laplace transforms, that total derivatives are represented as matrices, optimization of volume, and other crucial things. They just know how to memorize is proofs. This is both useless and unfair.

Worst professor I've had. Lectures were disorganized, no lesson plan, heavy accent and unreadable handwriting. Spent ages on old 3A/3B topics, then rushed new 6A material andskipped 2/3 of 6A content. Midterm average in the 30s. No practice exams, wrong examples, ignored questions, and called things “obvious” without explaining. DO NOT TAKE!!!!!!!!

First 3 weeks in class, spoke in mandarin chinese to an english fluent class. Only time this professor spoke english was to say the words "Partial" and "Zero". Throughout the class and homeworks, we worked on problems that applied the topics within the field of mutlivariable calculus. However the exams 7 hard proofs.The class averaged a 30 on exam.

Intro to calc class yet the exams were mostly proofs. Mostly did proofs in class and rarely showed examples of how to actually do math. No practice exams. Homework didn't match exams. Homework due dates/submission was unclear. Scattered teaching style. There was a large curve up at the end. Allegedly the last class started a petition to fire him.

Took him for Math 3A and he made it almost unnecessarily difficult to understand any concept. His accent is incredibly heavy making him nearly impossible to understand. He doesn't really know how to teach, he just starts writing on the chalkboard and doesn't explain anything. After writing something down he won't explain, and just say "y'know?"

will 100% take again (ill fail)

Very difficult to understand, and unhelpful.

Professor Yang was nearly impossible to understand verbally. He would also start progressively shouting towards the end of class which gave me headaches. He didn't teach necessary math8 concepts like truth tables or different types of proof. You just copy his examples and memorize them temporarily for a good exam grade. DONT TAKE, save your sanity.

People complain about the accent but honestly not even that bad. 1 midterm and 1 final make up your grade but the questions were exactly from homework and lecture. Use TA's sections and do the hw, you will be ok.

might be the worse teacher ive ever had. your grade is based on two things.. midterm and final. the grading is unfair and his teaching is horrible. accent is not understandable. good luck if you have to take him.

It's basically a self-study class. Final is worth 70%, midterm 30%. His teaching is terrible and he speaks english at a semi-understandable levelHe had 2 exam questions that Porter and Schley students didn't know how to do. He had 2 professors audit his class where they interrupted him 10x telling him what he was doing wrong.

Not very good, don't recommend

Professor was very out of touch and didn't teach well at all, but was also incredibly harsh and condescending. The grading system was 30% midterm and 70% final. There was no syllabus until multiple weeks into the quarter and he wasn't going to have a website or a canvas until the department made him. Learned everything from the text and TA.

For Math 4B he wrote small, could not understand and made the final and midterm worth your entire grade. He was terrible

AVOID!!!!! Had him for Math 4B, and it was horrible. First lecture 15 people walked out. He is very hard to understand, given his very strong accent and mumbling, he does NOT explain concepts even if we just heard about them, graded 50% midterm 50% final, and his lectures are just unhelpful. Don't make the same mistake I did by choosing his class.

Professor makes a bad first impression, was tempted to drop on first day. But, his accent is only a problem the first day, and he teaches things very clearly. You can choose to have homework included if it benefits your grade. Very comforting environment, ended up really enjoying the class and it really changed the way I think.
