Generally, college enrollment or credit before leaving high school does not disqualify a student from frosh admission or scholarship status. Both high school and college records will be used when applying to colleges.
It is only college enrollment or credit after leaving high school that may disqualify a student from frosh admission or scholarship status, but the exact criteria may vary from one college to another.
Note that if the student enrolls in a college after leaving high school and later applies to transfer to a different college or to graduate or professional school, any college enrollment or credit, including while a high school student, must be included in that application.
