1, the knowledge points are extensive and abstract: the knowledge points involved in postgraduate mathematics are very extensive, including advanced mathematics, linear algebra, probability theory and mathematical statistics. Some knowledge points are abstract and difficult to understand intuitively.

2, difficult and need to examine skills: the postgraduate entrance examination is difficult, and some questions require advanced mathematical theory and detailed calculation skills. Therefore, graduate students should not only have a solid grasp of various mathematical knowledge points, but also need the training of corresponding problem-solving skills and methods.

3. Time is tight: the total score of the postgraduate entrance examination mathematics paper is generally around 150, while the examination time is only 120 minutes, which requires candidates to answer quickly in a short time and ensure the correct rate, which increases the psychological pressure and difficulty of candidates.

4. Fierce competition: The competition for postgraduate mathematics is fierce. Generally, there are few enrollment plans for master of mathematics in universities, and the number of people taking part in postgraduate entrance examination is very large. Therefore, candidates not only need to deal with difficult problems, but also need to have certain test-taking ability and psychological quality.

5. Need long-term accumulation and persistence: It takes long-term accumulation and persistence to improve the math scores of the postgraduate entrance examination, and it takes a long time and a lot of energy to constantly do problems, sum up experience and adjust your learning methods.
