First of all, if you want to change your major, you must study hard in your freshman year. Every school has GPA requirements, and once it fails, there is basically no chance to change majors. Many colleges have restrictions on the number of transfer places, and only how many students can be transferred in one academic year. Then all students who change their majors will compete for the places given here. Moreover, if they change their major, they will definitely be transferred in, and they will also have interviews and assessments in all aspects. Only after the approval of the college teacher can the transfer be completed.
After changing majors successfully, you must make up the subjects you haven't studied in freshman year. This means that when others are playing, you should not only learn your original professional knowledge well, but also take time out to study independently and change your major, so you can't fail. Therefore, if you are dissatisfied with your current major and want to change your major, you should make a good study plan as soon as you start school, communicate with people in this major as much as possible, and get relevant experience information.
