Mathematics in Jiaotong University is a little more difficult than other schools. If you want to do well in the exam, it is recommended to refer to the papers of previous years and a yellow book of advanced mathematics exercises sold by Jiaotong University. There are also two sets of problem sets, A4 size is good, it seems to be "Analysis of Advanced Mathematics Test Questions of Shanghai Jiaotong University" borrowed by the library, which is quite old, but the questions are good. It is already difficult to practice after class. If you want to read textbooks, go to A300 and choose the one that suits you.
