Hi Gina and welcome to the forums! I hope you'll decide to register and stick around since as a prospective nursing student there's a lot of information to share here.
The first step towards becomming an RN is to check with the college or university of your choice to see if they offer degrees in nursing and find out what the requirements are to be accepted into the Department of Nursing.
I would strongly advise you to pursue a BSN degree (4 year) rather than a two year associate degree, but if you're unable to spend 4 years in school before getting to work then by all means look into the associate degree as a way to start out but plan to continue your education while working if you go that route.
Best of luck & let us know if you start nursing school ok?
