MATH4B . Tian W 2 Months Ago

This was a tough class. Quizzes in section as well as homework keeps you pretty busy throughout the quarter. Exams were all multiple choice which is unusually difficult for a math course because there was no partial credit. Final was much tougher than the midterm, this class requires a lot of studying to suceed, but the content isn't too bad.

Lectures are clear, grading policy is generous, exams are reasonable. You couldn't ask for a more straightforward and fair professor.

MATH4B . Tian W 11 Months Ago

Very good lecturer, I honestly did not need to put much time outside of the class to understand what was going on in class due to his lectures. Only negative thing is his quizzes he gave, but he had a very solid policy on it. Sometimes he would include stuff on his quizzes that we haven't covered.

I've taken Math 4A,6A so far and Math 4B w/ Prof Tian was the easiest. The practice midterm and final are similar to the real thing and Professor Tian is a great lecturer. My one only complaint is that he would sometimes forget to post the empty lecture notes before class and sometimes the homework could be a lot. There are quizzes in section.

Just a standard, pretty good professor. Not really much to say tbh; he won't amaze you, but he's solid. Exams are fair and very similar to the practice. No curve I'm pretty sure. Unlimited attempts on HW; 2 HWs per week. Only 1 midterm. Weekly quizzes which were mostly stupid.
