I'm happy that this thread was started, because although I applied to the one-year program (and was rejected!) I think ultimately, the 2-year would be better for me, given that I'll likely have to have some kind of income while I attend to school, and I'm also married with two cats and would like to be able to be home once in awhile.
I am anxiously waiting to see if I'll get into the 2-year program. I went to Stony Brook from 2006-2008 (I graduated early, thanks to a tremendous course load during those years, and transferring from Boston University, which is where I went as a freshman). My degree was in Psychology, and I'm 12 credits short from a second bachelor's degree in Philosophy (I decided not to finish it since it's almost as useless as a Psychology degree... in fact, MORE useless than a psychology degree! and because I graduated early, I was able to spend 6 months with my husband in Australia).
My undergraduate GPA was a 3.6. I got B+s in all of my prerequisites. Those grades aren't great, but I have been working full-time, and it was difficult to put a great deal of effort into the prereqs, as I took them at Nassau Community College after work. I volunteered/interned for one day a week from August until December at a nurse's office for a non-profit that I used to work for. Then I got a new job, and had to quit the internship.
I desperately want to go to school to be a nurse, and I had a wonderful experience at Stony Brook the first time around, so I'm hoping this works out. I think that I had pretty strong letters of recommendation and an excellent personal statement, but I think my grades are what kept me out of the one year program.
I'd also be interested in hearing what other applicants had in terms of GPAs and nursing experience!
