Difficulty analysis

In 2020, the mathematics difficulty of the postgraduate entrance examination has improved, but there are no strange questions beyond the scope of the examination, but the flexibility and calculation of the questions have been improved, further testing the patience, thinking flexibility and mathematical calculation ability of the candidates. This also tells us that the mathematics level of non-mathematics majors is getting higher and higher, and candidates should grasp the three main lines of analytic algebra and analytic geometry and pay attention to the intersection and connection between disciplines.

Comments on topic trends

In 2020, the mathematical questions of the postgraduate entrance examination will become more and more flexible, and the content of the probability part will become more and more comprehensive, so we can't be opportunistic. As an analytical subject for non-mathematics majors, advanced mathematics for postgraduate entrance examination tends to expand in the direction of geometry, and the geometry part should be paid more and more attention. As an introductory subject of algebra, line generation often breaks away from the essence of matrix regression algebra operation. To understand the meaning of linear transformation implied by matrix, we should understand algebra at a higher level.
