1, the principle of mathematics proposition for postgraduate entrance examination

Principle of scientificity and fairness: As a basic course of public education, the mathematics test questions for postgraduate entrance examination are mainly based on basic and life test questions, and try to avoid the contents that are too professional and abstract for the majority of candidates.

Principle of universal coverage: The content of the mathematics test questions for postgraduate entrance examination should cover all the contents required by the examination syllabus, especially the differences between numbers (1), (2), (3) and (4).

Difficulty control principle: the math test questions for postgraduate entrance examination should be above the average level, the pass rate should be controlled at 30-40%, and the average score (full score 150) should be controlled at around 75.

2. Postgraduate math review skills

The first step in math review is to read textbooks, which are the foundation and knowledge that must be paid attention to in math review, so we must master and use them well. When you have mastered the basic theorems, principles and formulas through the textbook, you should do the questions at the back of the textbook carefully, in order to test your mastery of the basics. When you encounter problems that you can't do or do wrong, you must really analyze and summarize them. It is better to prepare a wrong question book, which is far more important for later review than I thought.
