This may surprise many out there who think a nursing education is so substandard. But at the nursing school
I attended, at a university medical center, not only did we take classes such as anatomy and physiology, we had some of the same professors as the medical students. We also had human cadavers not cats. In addition, every RN who I have met who has gotten into med school has stated that they did quite well, especially in the clinical areas. Also many of them have said that the classes that so many premed students think are so hard (organ. chem, ect) are not that bad especially if you know how to study and you will certainly know how to study if you make through nursing school.
Yes, you will not have the science back ground that bio. and chem. majors have but you have more than the other med students who were not premed majors. But the clinical advantage will be big especially if you worked as a RN in critical care areas. For any bright RN who really wants to get into medicine it can be done, and you will find some advantages from your experience with a BSN. Don't listen to the typical premed student who has no clue what the education requirements are to become a RN. ONe more point anyone can declare themselves a premed student, now whether they can do well with organ. chem or physics is a different story. In contrast, the nursing program I attended selected 60 out of 450 applicants, now I am not saying that all the students could get into med school, but I do believe that many were definitely bright enough and had the academic accolades to do so. The other big advantage with a BSN is that you have already had an introduction to a professional type school that is very structured and demands discipline and hard work. Compared to many premed majors who are not use TO the academic rigors of a professional school.
