Xingtai medical college contacted the teacher with a single move. I want to ask if I am a single recruit and want to change my major.

The contact information of single-recruit schools in higher vocational colleges can be found on the school website, which is generally placed in a conspicuous place.

Under normal circumstances, it is not in favor of changing majors, unless you can give some reasons accepted by the school, such as being physically unwilling to study certain majors, or finding it unsuitable after one semester, and then apply for changing majors. Generally, when a university changes majors, the first year's grade is before the class 10%. You can transfer from science to liberal arts, not from liberal arts to science, and you need to report to the college.
