The content of postgraduate entrance examination is mainly advanced mathematics, linear algebra, probability theory and mathematical statistics. Among them, higher education accounts for about 56%, linear algebra accounts for about 22%, and probability theory and mathematical statistics account for about 22%. The full mark of the test paper is 150, and the test time is 180 minutes. Each question type and score are: 8 multiple-choice questions, 4 points for each question, ***32 points; 6 fill-in-the-blank questions, 4 points for each question, ***24 points; Answer 9 questions, ***94 points.
Second, what is the difference between one, two and three in postgraduate mathematics?
1, the test content is different.
Mathematics 1: The examination content includes advanced mathematics (function, limit, continuity, calculus of unary function, vector algebra and spatial analytic geometry, calculus of multivariate function, infinite series, ordinary differential equation). Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form). Probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, two-dimensional random variables and their probability distribution, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing).
Math II: Advanced Mathematics (function, limit, one-variable function calculus, ordinary differential equation). Linear algebra (matrix, matrix, vector, linear equations, eigenvalue and eigenvector of matrix).
Math 3: Calculus (function, limit, continuity, univariate function calculus, multivariate function calculus, infinite series, ordinary differential equation and difference equation). Linear algebra (determinant, matrix, vector, linear equations, eigenvalues and eigenvectors of matrix, quadratic form). Probability theory and mathematical statistics (random events and probability, random variables and their probability distribution, two-dimensional random variables and their probability distribution, numerical characteristics of random variables, law of large numbers and central limit theorem, basic concepts of mathematical statistics, parameter estimation and hypothesis testing).
2. Different majors apply
Mathematics 1: Applicable majors include mechanics, mechanical engineering, optical engineering, instrumentation and technology, metallurgical engineering, power engineering and engineering physics, electrical engineering, electronic science and technology, information and communication engineering, control science and engineering, computer science and technology, civil engineering, water conservancy engineering, surveying and mapping science and technology, transportation engineering, ship and ocean engineering, aerospace science and technology, and armament science and technology.
Materials and engineering, chemical engineering and technology, geological resources and geological engineering, mining engineering, oil and gas engineering, environmental science and engineering and other first-class disciplines have higher mathematical requirements for the two disciplines;
The first-class discipline of management science and engineering in the field of management science.
Math II: All two disciplines of textile science and engineering, light industry technology and engineering, agricultural engineering, forestry engineering and food science and engineering are applicable.
Mathematics III: All two disciplines and majors of the first-level discipline of economics theory and economics are applicable;
Applied economics in economics: statistics, quantitative economics, national economics, regional economics, industrial economics, finance (including taxation), finance (including insurance), international trade, labor economics and national defense economics;
Management engineering management level discipline 2 disciplines; Enterprise management (including financial management, marketing and human resource management), technical economy and management, accounting and tourism management;
Both disciplines are in the first-level discipline of agriculture, forestry and economic management of management.
3. Which is easier, one, two or three?
Mathematics-linear algebra, advanced mathematics, probability theory and mathematical statistics all need to be tested, which is relatively comprehensive and difficult, with linear algebra accounting for 22%, probability theory and mathematical statistics accounting for 22% and advanced mathematics accounting for 56% at most. The 123 middle school has the widest scope of investigation, and basically the whole textbook has to be tested, which is the most difficult.
The examination content of Math II is only linear algebra and advanced mathematics, of which linear algebra accounts for 22% and advanced mathematics accounts for 78%. The range of linear algebra in Mathematics II and III is roughly the same, while in advanced mathematics, Mathematics II has been deleted a lot, such as vector algebra and spatial analytic geometry, triple integral, curve integral, surface integral and infinite series, which are not tested, so it can only be called the simplest of the three numbers without reviewing this aspect.
The proportion of examination contents in Math III is the same as that in Math I, which also requires linear algebra, advanced mathematics, probability theory and mathematical statistics, among which linear algebra accounts for 22%, probability theory and mathematical statistics for 22% and advanced mathematics for 56%. However, compared with the first one, the third one does not investigate vector space, analytic geometry, triple integral, curve integral and surface integral, and all applications related to physics are not investigated, while calculus is more investigated. Compared with the number one, there is no hypothesis test and confidence interval in probability statistics.
Fourth, how to review the mathematics for preparing for the postgraduate entrance examination?
1, combing the teaching materials
The task in the early stage of math review for postgraduate entrance examination is a bit heavy, so we need to read the math textbooks carefully, and we must be familiar with important theorems and concepts. During the postgraduate entrance examination, review time should be planned every day, and mathematics is the most important part. Mathematics is the first step towards the success of postgraduate entrance examination. Mathematics for postgraduate entrance examination accounts for half the sky. Poor math review means that there is almost no chance of success unless you protect your research.
2. Check for leakage and fill the gap.
This stage varies from person to person. Students who have better math review can brush other databases and do it in strict accordance with the requirements of the exam. The topic may be difficult, but don't give up easily. This is to train you to control the examination time reasonably, and to check and fill in the gaps.
Students who review badly should pay special attention. This stage is especially important for you at present. You need to focus on the topics in the primary textbooks, focusing on the topics marked. This is the ability to train you to actively analyze the topic ideas and write down the knowledge points.
3. Real question training
During this period, everyone will do real questions for one or two days, strictly self-test and control the time. However, there are many subjects to review during this period, and the time will be tight, but don't give too little or put down the time for mathematics. Arrange the math review time reasonably every day, take out the real questions that have been done before, and do the questions that can't be wrong or wrong again carefully, so as to check the leaks and fill the gaps, that is, master the ideas and methods.
