According to the requirements and the latest spirit of the Mathematics Examination Outline formulated by the Ministry of Education, the author has deeply studied the characteristics and trends of postgraduate entrance examination in recent years, combined with his years of mathematics marking and his experience in tutoring "postgraduate entrance examination classes" in most cities in China.

This book "A Review Book of Postgraduate Mathematics" and its supporting article "400 Classic Questions of Full Simulation of Postgraduate Mathematics" are compiled. When writing, the author pays special attention to the combination with the students' reality and the requirements of postgraduate entrance examination.

It consists of the following four parts:

First, content summary and tips on important and difficult points-the purpose of writing this part is mainly to make candidates clear about the key points, difficulties and common test sites in this chapter, and to make candidates clear about the relationship between various knowledge points, so as to have an overall understanding and grasp of the contents of this chapter.

2. Explain the main points of exam knowledge-this part comprehensively expounds the knowledge points required by the syllabus, analyzes the key points, difficulties and common test sites of the exam, points out the common problems and mistakes of previous candidates when using basic concepts, formulas, theorems and other knowledge to solve problems, and gives corresponding precautions, so as to deepen the understanding and correct application of key contents such as basic concepts, formulas and theorems.

Third, common questions and their problem-solving methods and skills-this part summarizes the common questions in the unified examination over the years, summarizes the problem-solving methods of various questions, and pays attention to multiple solutions to one question, so as to broaden the candidates' problem-solving ideas, make the knowledge they have learned comprehensive and solve problems comprehensive and flexible.

Fourth, the question training and solution-this part selects the right amount of self-test questions and has detailed answers. Only a proper amount of practice can consolidate the knowledge learned, and math review must be done. In order to make candidates better consolidate their knowledge and improve their practical problem-solving ability, the author specially optimized and designed practical training questions similar to the real questions to be written in the book "400 classic questions of fully simulated mathematics for postgraduate entrance examination" for candidates to choose.
