The volume belongs to the basic part, and the difficulty of the question is relatively simple; The high score guide is a promotional article and a must-read book, which is somewhat difficult. The stereotyped version of this book is more comprehensive and systematic. Some knowledge points were deleted from the Guide to High Score in Mathematics, and the contents of the same test center were split. Simply put, it is divided into foundation and reinforcement. When learning, I feel that the knowledge points are scattered and not systematic enough. As far as the examples in the book are concerned, the mechanical engineering edition's mathematics papers are divided more carefully and correspond to the test sites, while the mathematics high score guide is generally divided into basic and strengthening, and the topics are more differentiated but not so corresponding to the test sites; As far as the test questions in the book are concerned, there is no distinction between the mechanical version of the math volume, and simple questions and difficult questions are mixed together. Mathematics high score guide is divided into two stages: basic strengthening, and the discrimination is obvious.

The course of mathematics fascicle of mechanic edition basically only talks about the test sites and topics corresponding to books, and the knowledge points are only touched. Personally, I think the class is inefficient and there is no way to test whether I have mastered it. It is only suitable for students with particularly poor math foundation. I suggest you do the problem before class. The course "Guide to High Score in Mathematics" explains the knowledge points in detail, and some teachers, Chen Jian, will supplement the contents outside the book. It is suggested that after listening to this part of the knowledge points, do your own questions and continue to attend classes.
