Though the explanation aren't as clear as I want to, but she put in a lot of effort to make things easy to understand, which is really a nice professor. Also, the homework and exams in general are easy to pass.

Very Helpful, straightforward tests, nice person. Overall a refreshing member of the UCSB math department.

The tests were straightforward and reflected practice and homework. She answered my emails and questions promptly and even followed up to make sure I wasn't still confused. Her lectures are a good pace and she mainly focused on core concepts.

Best math professor I've had at UCSB. Lectures are super clear with homework that gives good practice of the concepts. Weekly quizzes that are easy As if you did the HW. Midterm and final both had practice tests that were very similar to the actual thing.

The midterm was super easy and the final was very fair too. If you do the practice tests, the tests are very similar to them. There are two homework assignments per week, one after each lecture that are not too long. She is also always available over email to answer questions. Overall, this was a great class.

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

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.

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.
