First of all, changing majors requires the consent of both departments, especially those with large differences between departments and majors. Generally speaking, the transferred college should organize the examination of basic disciplines and professional knowledge; It is relatively easy for our college to change majors, or turn to unpopular majors; Some popular departments have high requirements for transfer students' grades and few places; It will be more difficult for liberal arts students to change to science or engineering, and vice versa.
Secondly, the number of people is limited. Colleges and universities have regulations on the number of places to transfer majors, which are generally controlled at 10%-20% of the total number of students in the whole year, and some are lower. It is understood that Lanzhou University stipulates that the number of college transfer students is generally controlled within 5%- 10% of the total number of students in the whole year. Therefore, students who want to change their major will face competition for places even if they pass the exam.
The third is the restriction on students' grades. Many students who have changed their major experience lament that those with good grades will change their major smoothly, while those with poor grades generally have no chance unless they have some patience and perseverance. It is understood that most colleges and universities require excellent grades for students who change majors.
