Secondly, the understanding in postgraduate mathematics is that unimportant knowledge points may produce fill-in-the-blank questions and multiple-choice questions, but it is unlikely to be admitted; The biggest possibility of understanding is to fill in the blanks and multiple-choice questions, or to solve problems with small knowledge points; Mastery and learning are roughly the same, but it is extremely important. If you don't take the exam every year, it won't be a postgraduate math!
The provisions made in the mathematics syllabus for postgraduate entrance examination are only relative (individual knowledge points such as indefinite integral and definite integral must be tested every year), so I think the focus of postgraduate entrance examination mathematics is the knowledge points tested in the last three years and your weak knowledge points!
Finally, I'm sorry, I don't know how many times you took the exam, because the contents and knowledge points of the two exams are very different, but it's still very difficult to count the points of the exam. There are three books (probability of generating high number lines and mathematical statistics), but the content of the first test is far more than that of the third test (especially probability and mathematical statistics)! Because I was the top student, its structure includes advanced mathematics, linear algebra, probability theory and mathematical statistics, accounting for 56%, 22% and 22% respectively. My math review method is to classify and summarize each part, and then develop and train the details. For example, I divided the contents of Chapter 12 of Shu Gao into four parts. The first one is the first chapter of function, limit and continuity (preparation knowledge); The second is analytic geometry, which is embodied in plane and space. Chapter 8 (transitional knowledge); The third block is that calculus contains three parts (core knowledge), the first 1 part. Chapter 2, 3, 4, 5 and 6 of unary function. They are derivative and differential, application of derivative, indefinite integral, definite integral and definite integral. The second part. Chapter 9, 10 and 11 of multivariate function. They are differential calculus, multiple integrals, curve and surface integrals of multivariate functions; The third part. Chapter VII Differential Equation; The fourth block is series (power series and trigonometric series), and chapter 12 (expanding knowledge). Through this division, I clearly know where the focus is, where the frequent test sites are, and where the difficulties are. At the same time, I also know their relationship. In fact, the whole university mathematics mainly studies dynamic changes, and the limit is its soul, which permeates every detail. As for the reference books, I just read the learning materials repeatedly, systematically review them, find out my own advantages and disadvantages through the test and training of real questions, and then implement targeted supplements and enhancements. In the whole process, we should learn to summarize some important knowledge points, so that it will be easier to review them later. For the wrong question, we should analyze the cause of the error and then answer it. Mathematics is the problem, and the problem is the driving force for progress. Let's enjoy the wisdom brought by math problems together!
But in any case, I hope you must analyze the real questions and see which knowledge points are often tested, and you are not very familiar with them, so these knowledge points are the top priority of your review! Wish you success!
