Because there are too many math subjects.
First of all,
You have to decide which school and what major to take for postgraduate study.
At present, the majors in the School of Mathematics are divided into very fine lines.
Generally there are basic mathematics, computational mathematics, probability theory,
Mathematical statistics, mathematics education and other majors.
There are many small directions under each major.
The subjects to be tested in different schools and majors may vary greatly.
But mathematical analysis and advanced algebra are generally tested.
The other is English and politics.
In addition, schools that set questions according to their own needs,
From real variables, probability statistics, functional, ordinary differential,
Complex variable, functional, topology, advanced geometry, substitution and other subjects.
Choose one or two questions for a preliminary test.
Choose one or two questions in the second interview.
Secondly,
Textbooks are easy to understand,
Flip through reference books,
Of course, preparing for the exam still depends on the real questions.
Carefully study the questions you wanted to take in school in previous years,
Do it n times, the bigger the n, the better.
Three,
Keep your body and perseverance,
Postgraduate entrance examination = examination,
The double test of physical quality and psychological quality,
A momentary fever is not a skill,
Sticking to the end is king.
