Hi,
I don't know about the other schools, but for Nassau they only look at your grades from classes that apply to the nursing program. They calculate your GPA based on that. My overall GPA from my 1st bachelor was 3.4, but luckily I got good grades in the classes that did transfer. I took all the pre/co reqs and ended up with a 3.95. To see a list of the classes clik on the link and scroll to the bottom.

Also, I know that they prefer it if you are done with most of the pre/co reqs instead of applying with just the pre reqs completed.
I got ino their evening program for Fall 2008 and can't wait to start. Good luck.
