Okay, I understand now. College-wise, the short answer would be mostly no. There will be a list of prereq undergraduate courses that are mostly the same but will sometimes vary slightly from school to school. Example: I believe Johns Hopkins requires 2 semesters of Calculus based Physics but most other medical school only require trig based physics. Many of the courses required to get your RN should overlap with the required medical school prereq courses but there may be a few you will have to take (maybe another semester or two at most of undergraduate school). I highly recommend starting studying for the MCAT at least 2 years before you plan on taking it so factor that into your time as well.
