According to the research policy of Northwest A&F University, students can choose to change their major when studying. Students need to indicate their wishes in the application materials for insurance research, and provide sufficient reasons and relevant supporting materials. The school will evaluate the feasibility of students' application and major adjustment, and finally decide whether to agree with students to change majors. Such a policy aims to give full play to students' potential and interest, so that they can better develop their academic and career paths.
