1. First go to official website to find out whether the school has a policy of changing majors, and confirm whether your major and the major you want to change can be changed.

2. If the school doesn't have the policy of changing majors, it is not possible. It is suggested to change schools. If so, it is recommended to study hard and improve GPA (generally, GPA is required to be higher when changing majors), and then pay attention to the time and relevant notice of changing majors.
