It seems to me you have a pretty good foundation to enter any nursing school
. I understand you being nervous, but I advise not to limit yourself to one institution. No institution is perfect and many can help you reach your goal. Granted, you need to ensure the school you choose to go to is accredited, otherwise you may end up spending a lot of money for nothing.
I suggest you visit the National League of Nurses website to view which schools
are accrediated by them. The web page is http://www.nlnac.org/Forms/directory_search.htm
Once you're there, select your state, the program type, click "Search" and voila!
Once you have a list of possible locations, look them up online and read up on their programs. If you have the time, I suggest visiting the campus and ask nursing students about the good and not so good things about the program. You will get a lot of feedback, but it will be your job to discern which complaints are valid and which are not. Then decide what is good for you.
Good luck !
