I am currently going to a 4 year university and considering a pre-med major, I am basically in my second year with no upper division type work (I just recently picked a major). I do not know much about the different "specialties" that medical carreers are divided into. My questions: When does a student decide what specialty field they want to go into? How can I learn more about each field? Is thier a chance to try different fields before choosing one?
