Hi Danielle! Do you know what school you want to go to? I would start by researching the nursing programs at all of the area schools, etc, that you are interested in going to. Each school has different requirements. I live in a very small town and will be in a 2-year course at a local community college to get my ADN. Of course, you are encouraged to take as many "core" classes for your degree (history, psych, english, etc) as possible before actually applying to the nursing program. We also have to take Microbiology and Anatomy and Physiology prior to application. (Since I'm only able to take classes part time right now, I will have been in school 5 years before it's all said and done: three years for core classes and pre-requisites, and two years full time in the nursing program.
) Most schools also have you take an entrance exam.
Like I said before, the program I'm going into is a 2-year program. After the first year you have to test and be licensed as an LPN to go onto the second year, after which you are ready to try for RN licensure! If you go for your BSN in a four-year program it may be different, but I'm not sure.
The main thing would be just to scout out the schools that you are interested in and talk to the nursing department staff. They'll let you know what the best course of action is for you. Also, remember that a lot of schools have lots of people applying for a small number of spots, so many may have a waiting list. Good luck, keep us posted!
