Pick a college that suits your personality and a major that interests you. You will need to get good grades in college in order to apply for medical school. At the medical school I attended, the average GPA is reported to be 3.85, so even one or two B's can hurt your chances of acceptance.
Medical school takes 4 years to complete.
At the end of medical school you can apply for a residency in Radiology.
