Best of luck!
I am a clinical pharmacist, however, when I started college I planned to go to medical school. The path is the same really. I changed my mind sophomore year and switched to pharmacy. If you want to go into the medical field, you should be sure to take biology, chemistry and math classes. You don't have to major in a science, but you have to be sure to take all of the courses required for the field that you choose to pursue after undergrad. So be sure to check the requirements for the programs that you want to apply for.
