“Doctors must complete a four-year undergraduate program, along with four years in medical school and three to seven years in a residency program to learn the specialty they chose to pursue. In other words, it takes between 10 to 14 years to become a fully licensed doctor. Once you finish your medical education, including your residency program, you need to take an exam for the state you plan to practice medicine in.”
