"Specialized Health Sciences" majors post the worst MCAT scores (
https://www.aamc.org/download/321496/data/factstable18.pdf) and probably not by coincidence have the worst admission rates. I believe it at least partially stems from ideas such as this. I applaud your desire and drive to make the transition from nursing to medicine (I'm on the same path), but there are no shortcuts. Many nurses (this may not include yourself but I post as a notice to others considering this), especially those in academia, would like to think the nursing school pre-reqs are similar in rigor or breadth to pre-medical requirements. Don't be lulled into a false sense of security because this simply isn't the case. Even if you could do this, would you really want to? We are at least in part on this journey to truly understand the science behind what we've been doing and seeing, so dive in and devour every last morsel of it. Even the pre-reqs.
Sigh. Sometimes they are EXACTLY THE SAME. Depends upon the program. Core curriculum for Gen Bio I & II is same across the board. Same thing for Gen Chem I. You have to check to be sure, but there are programs that will not allow students to take the required Microbiology or A&PI and II, needed for nursing programs, if they do NOT first have the pre-requisite Gen Bio, etc, which is determined by the Dean of those sciences at the particular school.
The student should check to be sure it is the same pre-req Gen Bio and Chem that is required for a degree in a Bio or Chem program of study. Everyone assumes there are dumbed sciences, but this is not at all necessarily so. It is very school dependent, and you have to find this out for your particular program. Again, many schools, regardless of the declared major, will not allow registering for Microbiology or A&P I & II w/o the required Gen Bio curriculum, which is standardized as a pre-requisite for entry into the Micro or A&P class.
So check out YOUR program for yourself to find out how these courses roll.
So if your college required General Bio, for example,in order to meet pre-reqs for Microbiology, regardless of your major (nuclear med tech, RT, nursing, etc), if you did well in it and it truly meets the curriculum requirements, unless you want to re-take to refresh, you're good. ONLY you can meet w/ academic advisor and check this out for yourself. Not anonymous strangers on SDN.
After that, take all the rest of the science pre-reqs and some higher math, stats if you haven't had it, but you probably have or will have to take it--don't know a BSN program that does not require stats in order to take the other research courses. So depending upon your college/program, if you haven't taken Gen Bio II, Chem II, Organic I & II, Physics I &II, take those courses first before the MCAT. Also take Biochem. You will have been required to take the necessary social sciences, unless someone is now trying to say they are some "dumbed down" version also.
I also recommend some higher math courses--at least Algebra and pre-Calc. So, regardless, you still have a course work you must take, in which you must understand fairly well, and in which you must do well (sGPA).
Good luck
