The proportion of different departments to major is not consistent, and the proportion of generally better majors is relatively large. Generally, students whose total grade in the first academic year is before grade 1%-3% can apply to the counselor and fill in the application form when registering in the second academic year. If 1%-3% of the students before grade, that is, those who have the qualification to change majors, do not apply, the quota will be invalidated immediately and cannot be pushed down according to the ranking.
Of course, although the regulations of the Academic Affairs Office are quite strict, Zhengzhou University is not strict about students changing majors. If you have good connections to use, it's easy to change your major. Moreover, it can be changed when studying public courses in the first semester, which will not affect the study of professional courses in the future and reduce the learning burden.
However, the courses offered by basic medical college, stomatological college, public health college and nursing college in the first academic year are basically the same. Freshmen and sophomores will not encounter difficulties in making up specialized courses. Since you are determined to change your major, it is safe to do a good job in the first school year, whether for changing your major or for future development.
Wish you success!
