It takes 4 years of undergrad or 3 if you graduate early, 4 years of med school. After med school you have residency in which at this time your getting paid but you are practicing in the field you want such as dermatology for 5+ years or so i forget how long it is. Also, during med school you have electives/rotations and you will be able to try other specialties, so don't set you mind on one specialty and don't set your mind on one med school.
Pre-med requirements during undergrad are bio 1/2, general chem 1/2, organic chem 1/2, physics 1/2, English, Math and upper level science courses are recommended such as biochem etc.
Try to finish all the activities i listed before your junior year in college, because that is when you will apply to med schools, summer of your junior year, and that is when you will Take your MCAT also, the medical admissions test.
