I don't know how many science classes you get in a psyche degree. I went back to school in 1995. I graduated in 1984 with a B.S. in Business Administration. I had always wanted to be a nurse or a pt so I started nights in 1995 and took the required prereq sciences, bio, A&P 1 and 2, Chemistry and Microbiology. I worked 30 hours a week while I did this as a single mom. When it came time to go to Nursing School, I could have opted for a two year degree to get an associate or 3 years to get a BSN. I don't know how you possibly obtain a BSN in one year and learn the material and skills you need. I graduated last May, and I am glad I had the three years because I was able to study the material, digest it and experience all the different clinical experiences. Believe me, I was nervous too, I was 35 going back. I was the oldest in my class. I would not recommend what you are planning to do. Nursing is a very stressful job and very very different from school. Once your on your own, you are the nurse, you develop the plan, it is your license, you have to talk to the patients and the family. I understand you wanting to get "it over with", but you are doing yourself a disservice by pursuing this path. My transition was tough and I am now 39, I have a lot of life experience to draw on. Don't be too tough on yourself. Give yourself time to absorb your material and still have a life. You are so young. Don't rush it through. If you want to be a nurse, you are obviously a special person, take care of yourself, and give yourself time to get through the program. If it takes two years or three, it really doesn't matter. but don't burn out before you start.
