You just need to apply to the college to change your major. With the approval of the academic affairs office of the school, you can study in this major without paying money.

Article 18 of China's Regulations on the Management of Students in Colleges and Universities stipulates: "Students can apply for changing majors according to the regulations of the school. It is approved by the school that students change majors. Schools can adjust students' majors appropriately when necessary according to the development and changes of social demand for talents with the consent of students. "

According to the different conditions of colleges and universities, there are roughly three situations in which candidates choose their majors again after entering the university.

1. 1. Relevant experimental classes in colleges and universities select students for freshmen.

2. Second, departments that enroll students by major category should choose the major direction in the second and third grades.

Third, freshmen are allowed to change their major once or twice after completing their studies for one or two years.

There are various restrictions on changing majors, the first is the faculty restrictions. The transfer of departments requires the permission of both departments, and the general transferred departments will also organize tests. Not all departments accept transfer applications. Generally speaking, it is relatively easy to transfer to a department major or an unpopular major. However, some popular departments, such as economic management, computer science, psychology and so on. There is a high demand for transfer students' grades and a very small number of places.

The second is the quota limit. The transfer quota stipulated by colleges and universities is generally 10- 20% of the total number of students in the whole grade.
