This book is divided into 18 lectures according to the knowledge points frequently tested in the syllabus. The contents of the book are all independently written by teacher Zhang Yu, so the title is "Zhang Yu Advanced Mathematics 18 lectures". Each lecture is divided into four modules: the requirements of the syllabus, detailed lectures, detailed answers to examples and refined exercises.

Zhang Yu's eight sets of papers and four sets of papers are difficult for many people to reflect, but I think some so-called questions are adapted on the basis of after-school questions, even the test sites are the same. I think it is difficult because it is not the usual test center, but everyone's weakness, so I think it is difficult. If you master the knowledge points in the textbook, there will be no difficulty.

According to my experience, the first round of study should be solid, and how to define and prove most theorems should be understood as much as possible (only understand most, not all, because some proofs are beyond the class).
