I am discovering that every single school has different requirements. I have a notebook for each different school that I'm applying to because otherwise I'd go crazy trying to keep it all straight.
Have you looked into academic forgiveness? Most schools have some form, particularly if you are returning after a long break (usually more than 5yrs) and you can have one, two, or sometimes all semesters of your grades "forgiven". Of course you lose the credits for those classes, but if it's something that will keep you from getting in to NS at all, it could be worth re-doing it. Your original grades still show when looking at your transcripts, but they don't count when factoring your GPA

I'm trying to get two bad semseters (my brother died that year) forgiven so I can be competitive for the programs I want.
One of the private schools in my area has no waiting list for the nursing program, you just have to have an overall gpa of 3.0. If you do the ABSN program, then you have to have b's in your sciences.
