Both the number one and the number three are distributed around the difficulty range of 0.4~0.6, and 0.4~0.6 is a medium difficulty test, so the mathematics for postgraduate entrance examination is mainly medium difficulty. More specifically, in the difficulty interval of general examination, the scores of 0.4~0.6 and 0.6~0.8 add up to at least 1 10, which is what we call basic questions.

Therefore, the test questions of the postgraduate entrance examination for mathematics must be based on basic questions, which means that as long as we can lay a good foundation and play as many basic points as possible, we may get high marks. In our annual review, our main task must be to ensure that we don't lose points on the basic points as much as possible. On this basis, you can do some comprehensive questions in moderation as the general direction of review, and high scores are in sight.

Matters needing attention in postgraduate mathematics

Postgraduate entrance examination consists of advanced mathematics, linear algebra and probability and mathematical statistics. The full mark of the test paper is 150, and the test time is 180 minutes. Postgraduate entrance examination mathematics requires candidates to master four algorithms of derivatives, the derivation rules of compound functions and the derivation formulas of basic elementary functions. At the same time, the postgraduate mathematics requires candidates to understand the four algorithms of differentiation and the invariance of the first-order differential form, and will find the differentiation of functions.

If you feel that what you have done is wrong, you must immediately check what you have done before to see if there are any miscalculations or improper use of methods, such as the choice of coordinate system and integration order of double integration, and whether symmetry can be used.
