2. First of all, the most difficult and simplest questions in the postgraduate mathematics subjects are basically not tested. The nature of postgraduate entrance examination is a selective examination, so a basic principle of postgraduate entrance examination proposition is to have a degree of discrimination. In this sense, it is meaningless that a topic is too difficult and too simple.
3. Secondly, the difference between Math 1 and Math 3 is not obvious, which may be different from the impression of many candidates. The difference between Math 1, Math 2 and Math 3 is mainly reflected in the scope of examination, and there is little difference in the comprehensiveness and flexibility of the test questions.
4. Finally, the overall difficulty of the postgraduate mathematics is analyzed, and it is found that the number one and the number three are distributed around the difficulty range of 0.4~0.6, while 0.4~0.6 is a test with medium difficulty, so the postgraduate mathematics is mainly with medium difficulty. At the same time, in the medium general direction, it is found that the score of 0.6~0.8 is much more than the score of 0.2~0.4, so the overall difficulty of postgraduate mathematics can be summarized as: medium easy. 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 for the postgraduate entrance examination are absolutely based on basic questions, which means that as long as we can lay a good foundation and strive for as many basic points as possible, it is possible to hit high scores. In the annual review, the main task must be to ensure that the basic points are not lost as much as possible. On this basis, do some difficult and comprehensive topics in moderation, which is the general direction of review and is expected to get high marks.
