First of all, grasp the key points through the outline. Before this year's outline comes out, summarize some basic theorem concepts and methods through last year's outline. Mathematics is a logical science, so it is very important to have a deep understanding of basic concepts and be familiar with the questions and problem-solving ideas of common test sites. Although you can't get high marks by this alone, it is the basis and prerequisite for getting good grades. Only by firmly remembering the basic theorems and formulas, can we have our own ideas and breakthroughs when doing problems, and we can easily deal with them. In recent years, the lack of basic concepts, theorems and methods in mathematical statistics for postgraduate entrance examination is a key point of losing points. If you want to get high marks, you must first put these basic things in order.
Secondly, we should strengthen the training of comprehensive problem-solving ability, apply basic knowledge to practice, and strive to make a breakthrough in problem-solving thinking. Specifically, it is necessary to seize a number of test sites that can collectively reflect and synthesize various knowledge points and make key breakthroughs. The practice of test questions can help you test your review effect. Considering the characteristics of mathematics, it is very difficult to ask candidates to think clearly about all the test sites and give relevant problem-solving ideas. This problem can usually be solved by consulting experienced teachers, attending remedial classes with good reputation, or reading relevant remedial books.
