I took this in my first semester as a first-year. If I hadn't just taken calculus in high school a few months prior, I probably wouldn't have done as well. There are a lot of resources for extra help and practice but sometimes it's overwhelming because the pace of the course is fast. It also feels tedious to do the homework (which is the best form of practice). Yaolong is an average-good teacher, he's open to questions and his work is easy to follow. The course takes a lot of self-initiative if you don't follow what's going on. Don't take this class unless you really need to fulfill a pre-req. #tCFfall2021
