It depends on your foundation and math. As said on the first floor, the main content is calculus, which is the only subject I took twice in 15 course, but my math is very poor. First read the book carefully according to the outline, then do the exercises after class, and finally do the real questions over the years and buy a set of exercises. Personally, I think it is best to analyze the exercises in previous years and do them carefully. Because there are many papers, I am very sensitive to the topic. Isn't that to say that I can't let go? If you do the above, you will get by. This course, like English (2), is a down-to-earth basic skill with nothing. Good luck!
