Although requirements vary from program to program, a BSN can help prepare you to enter medical school, since some of the course load may be similar. According to the Association of American Medical Colleges, before applying to medical school, students should complete the Medical College Admission Test (MCAT) and demonstrate that they can handle rigorous coursework. Some schools require applicants to complete premedical course requirements while others have moved to competency-based admissions. It is important to review the specific requirements for each school.
