In 2022, the second average score of mathematics for postgraduate entrance examination was 7 1.87, and the difficulty coefficient was 0.479, which was slightly more difficult, slightly less than 5438+0 in 2026, but not obvious. Advanced mathematics and linear algebra are the examination subjects of Math II for postgraduate entrance examination. Generally speaking, Math 1 is the most difficult, followed by Math 3.
The best comparison of one's postgraduate entrance examination scope is as follows:
Number one and number two are two different mathematics subjects for postgraduate entrance examination, and the examination scope is somewhat different.
First of all, the contents of Exam No.1 and Exam No.2 are similar, including advanced mathematics, linear algebra and probability theory. But counting one is more than counting two.
In advanced mathematics, the number one covers a wider range, including vector algebra, multivariate function calculus, ordinary differential equations, Fourier transform and so on. , and number two only involves vector algebra, multivariate function calculus, ordinary differential equations and other parts.
In the part of linear algebra, number one covers more extensive contents such as matrix, determinant, vector space and linear equations, while number two only covers matrix and determinant.
In the part of probability theory, number one covers more knowledge of probability theory, including random variables, random processes, law of large numbers and central limit theorem, while number two only covers random variables and random processes.
In addition, the test difficulty of No.1 and No.2 is different. The examination of the top scholar is more difficult and the questions are more complicated, which requires candidates to master more mathematical knowledge, methods and skills. The test of number two is relatively difficult, which mainly examines the basic mathematical ability and mathematical literacy of candidates.
In short, there is a certain difference between the examination scope of number one and number two, and the content covered by number one is wider and deeper than that of number two. When choosing examination subjects, candidates should choose suitable examination subjects according to their own mathematical foundation and ability.
