Nurse Practitioner Schools

In the 17th and always wondered what I would do. since I was a little girl I always wanted to be a doctor, but my grades in mathematics are not high (C's, 75-80) so my cousler said it was not a good idea. But I was amazing to biology in the last year and I'm very good in chemistry this year. I have all A's and my overall average is a B + for the AI always seemed to be a nurse practitioner. What is a good inexpensive College in New York, New Jersey, Connecticut and Pennsylvania that this program works.
