Well I'm not from the States, I'm in Northern Ontario and out here we have a program called Pre-Health that guarantees you're a shoe in, into the Nursing Programs
before anyone else.
This is the path I decided on taking to make sure I got in. (I'm 28)
So maybe you should look into taking the Pre-Nursing to guarantee you a seat for the next year. It's worth looking into it if they give precedence to certificate holders of their program.
And I don't think it's for new highschool graduates, in fact the whole program (out here) is geared toward the health sciences,
so it offers a big advantage.
All classes are geared toward actual numbers and terminology you will be using in hard core Nursing program.
This is my opinion, our school does the same thing,
1- Their graduates from their program
2- Highschool students that have the req pre-req. (grade 12 diploma + 6 other courses)
3- Anyone else, that is looking for a change of career, have GED etc.....
