Comment: The exams do not match what he taught in class. There's some lucky problem that doesn't require anything we learn in the class which depends purely on luck, or some kind of smartness. Also, he seems arrogant to the students in his office hour.

Comment: Very helpful. Exams were a tad too time constrained for me. Enthusiastic and will write up solutions to his problem sets if requested. I would recommend him as a professor.

Comment: First off, Zhang is a pretty good lecturer. Unfortunately, Zhang has the idea that no one in the class wants to learn rigorous mathematics, so he skipped over quite a few topics that tend to be standards in other 113 courses. That would be great if I didn't want to go to grad school. But I do, so it wasn't. Office hours started off great for the semester. Zhang had 3 per week which is more than more instructors I've had, however he always had this arrogant demeanor about him. After a while I would stop going to office hours to ask questions because he made me feel like my questions we're not worth his time. Assignments were fine, definitely on the shorter side which I liked. His exams we're doable, although the midterm was a big time crunch. Overall I kind of regret taking 113 with him. Ultimately I feel like I missed out on a lot of great algebra.

Comment: One thing that i really didnt like about this class was that he didnt provide solutions for hw. (And he makes his own hw) Other than that, it was ok.

Comment: Knowing upper div abstract algebra or linear algebra is very useful for this course but you can do without it.

Comment: the exam averages are pretty low with a very tight spread, so make sure you actually participate in class because that 20% is really the only thing that will get you an A in the class (otherwise you should be content with getting a B+ max)
