Hello, those who leave the army and return to school can transfer to other majors after the school agrees and performs the relevant procedures. Under normal circumstances, colleges and universities in China allow students to change majors under the following circumstances: (1) Students do have special skills, and they apply by themselves and are recommended by their major. After transferring to the big exam, you can give full play to your specialties; (2) Due to a certain disease or physical defect, the medical unit designated by the school proves that you can't study the original major, but you can still study other majors; (3) The school thinks that there are some special difficulties and it is impossible to continue studying without changing majors. However, freshmen who have been enrolled for less than one semester, those who are above the third year of undergraduate or above the second year of junior college, will be transferred to public expenses at their own expense, and those who have no justifiable reason may not change their majors. Generally, it must be reported to the school education administrative department for approval or filing.
