I'm a senior in college right now...I go to Holy Cross in Worcester, MA. I'm graduating with a liberal arts degree with a major in Classical Studies. But...I've realized that I want to go into the nursing or some other medical field. What do I have to do to become a nurse? Do I have to retake all 4 years of college again in nursing? Or can I do a pre-med post bac program that lasts 2 years? very confused...
