1. Math:

Discipline characteristics: Mathematics, as an abstract and theoretical discipline, tests students' logical thinking ability and mathematical modeling ability.

Difficulties: It requires a solid mathematical foundation and logical reasoning ability, including advanced mathematics, complex variable function, mathematical analysis, etc.

2. Physics:

Discipline characteristics: It is necessary to deeply understand the laws of nature and master the basic theory and experimental skills of physics.

Difficulties: You need a deep understanding of physical concepts and the ability to use mathematics, including theoretical physics, quantum mechanics, electromagnetism and so on.

3. Chemistry:

Subject characteristics: Students are required to master the basic theory and experimental skills of chemistry.

Difficulties: the breadth and depth of chemical knowledge are relatively large, including organic chemistry, inorganic chemistry, physical chemistry and so on.

4. Computer science and technology:

Subject characteristics: Basic knowledge of programming languages, algorithms and data structures is required.

Difficulties: programming and algorithm understanding are the key points of assessment, which require high-intensity hands-on ability and logical thinking.

5. Economics:

Discipline characteristics: test the ability to understand and analyze economic theories and policies.

Difficulties: Economics includes macroeconomics, microeconomics and mathematical economics. It requires higher mathematics, logical reasoning and abstract thinking of practical problems.

6. Foreign languages and literature:

Subject characteristics: deep understanding and skillful use of foreign languages and cultures.

Difficulties: You need to have a broad understanding and mastery of foreign languages and literature, linguistics, translation, etc. At the same time, the language level is high.

These majors are considered to be more difficult, on the one hand, because the discipline itself is professional and theoretical, and on the other hand, because of fierce competition, it needs higher discipline literacy and comprehensive ability. For graduate students, it is most important to choose a major according to their own interests and actual situation, pay attention to the improvement of basic knowledge, strengthen practical ability, prepare for the exam systematically, and choose a suitable graduate major.
