Probably the easiest class I've had at UCLA. Homeworks were really short and quizzes/tests were pretty easy. She told us what topics to expect from the midterms and final, which made them even easier to study for. The class had two midterms and one final.

Prof. Wang is an absolute legend.
She focuses on the big picture in her tests, with like at least half the questions on exams coming from lectures, worksheets, and homework. The workload was really light. The thing is even though it's an easy class, I still feel like I learned the material and understand differential equations. I wish more classes can have stress free learning.

This class is very easy when compared to other UCLA math classes. All the HWs and Exams are very straightforward and you can use wolfram alpha to check a lot of your work especially for the first half of the class. 2 Quizzes and HWs are dropped so you can drop the longer/harder ones if needed. Highly recommend taking this class with this professor.

Easiest math professor I've ever had. If you want an easy A+ take her. The only bad part is that you won't really learn anything, but there's no material you couldn't self-learn anyways.
