Most successful applicants have had some involvement in their chosen field, either through employment or volunteer work. Many physicians, dentists and veterinarians are willing to have people observe them at work and most hospitals and clinics have organized volunteer programs that afford opportunities to associate with professionals at work. Good grades and good admission exams scores are not enough to gain acceptance to medical, dental, or veterinary school. Get involved in things outside the classroom. Volunteer work and undergraduate research have already been mentioned.
