Great professor!

MATH4B . Zhang Q 8 Months Ago

A WONDERFUL Professor. She is very good at what she does, teaches very clearly, and ACTUALLY SHOWS EXAMPLES. Even though it was at 8 am, Zhang managed to teach things very clearly. Tests were very fair in my opinion, very similar to practice exam. Would take her again, I hope i get her for 6A.

MATH4B . Zhang Q 1 Year, 1 Month Ago

Literally the best professor ever. Lectures are extremely clear and tests are similar to class material. Very nice too.

MATH4B . Zhang Q 1 Year, 4 Months Ago

Zhang was great for 4B!! All lectures were recorded and notes were posted on Canvas. Practice tests were given for the midterms and final and were almost identical. Only went to class the first day and the testing days and got an A. 2 homework assignments a week but only 10 questions. Material is relatively easy but does a good job explaining.

MATH4B . Zhang Q 1 Year, 5 Months Ago

Her detailed notes and great lectures make the course material easy to understand, and the HW assignments directly relate to the lectures, making them manageable. Lectures are recorded, so attending lecture wasn't necessary and practice tests resemble actual tests, which are fair and easy. One of the best profs at UCSB and my favorite of all time.

MATH108B . Zhang Q 6 Months Ago

TAKE HER OVER ANYONE. Upper division math classes can feel like a knight going on a quest to fight a dragon, but Professor Zhang is like an angel sent down to assist you in battle, and she will make sure you succeed. Potentially the best lecture notes ever, no surprises on exams, homework assignments actually help you understand the material. GOAT
