I'm looking at acc BSNs also. My top choice right now is UNLV, but I'm looking at a few other schools also (mostly back east/mid atlantic or southern area, where i'm from). It seems to depend slightly on the program. It sucks that you have a low GPA, but you can't change that now. Some programs are only looking at the courses they want- so it doesn't matter if overall you have a low GPA, if you have high courses in the classes they are actually looking at (for example, I have a C in Organic Chem, but UNLV School of Nursing only looks at Chem 108 or its equivalent) whether or not they're from your previous college. Other schools will weigh your science GPA more than your overall GPA. I got a C in my first pre req (my whole group failed. It was pretty much the worst group) and I'll be retaking some courses just to get my GPA up. Yes, it's a lot of money, I'm adding to my previous debt, and it's a lot of time (I'm still an "out of state" student, and I work two jobs, but neither add up to a career). But ultimately that seems like what I'll need to do to achieve my goal.
My plan is to take the pre reqs I can't get in without, and I've been taking them part-time to save money. Then, as I'm closer to being ready to apply, to take the rest full time (I have about a year left of pre req schooling with this plan). If I don't get in the first time, then I'll consider retaking classes I already have in order to improve my GPA.
