Fall 2019 - class wasn't too difficult bc i've taken calc before; but i can genuinely say that if i hadn't, this class would've been hell. prof is terrible at explaining & doesn't leave room for any student-teacher interactions. he seems like a super nice guy but just honestly not the best teacher. he posts his lecture notes on ccle (so honestly there's not that much of a point in going) & his TAs are super helpful.

Fall 2019 - Class attendance is not mandatory which is fantastic. Fan's first lecture did not leave a good impression, he basically just followed the textbook and sometimes gave confusing examples. I ditched all of the lectures after the first 2. I like this series which you can watch for free on youtube. ocw.mit.edu/courses/mathematics/18-03-differential-equations-spring-2010/video-lectures/lecture-1-the-geometrical-view-of-y-f-x-y/ The textbook can be downloaded for free online, don't buy it. The textbook is also hot garbage imo and I often ended up more confused after reading it than when I started. The TAs are a godsend in this class especially Snyder who was able to condense all of the material into his own lectures in a way more understandable way. The upside is that the tests are very straightforward and often easy or at least easier than the homework. So the class isn't too bad.
