Becoming a Doctor.
"Educational Program Requirements:
Becoming a physician requires completing medical school. Entry into medical school usually requires a bachelor’s degree or some other advanced degree. As a bachelor’s degree is typical of students before entering medical school, those students planning to attend medical school are often called “pre-med”. A pre-med undergraduate education focuses heavily on science, with courses in physics, biology, mathematics, English, and inorganic and organic chemistry. Many pre-med students also take courses in the humanities and the social sciences.
Formal education and training requirements for physicians are among the most demanding of any occupation. After completing four years of undergraduate education and receiving a degree, medical school applicants must take the Medical College Admission Test (MCAT). Acceptance to medical school is highly competitive. Once in medical school, students will complete four years of graduate medical education, which includes classroom, laboratory, and supervised clinical training; followed by three to eight years of internship and residency, depending on the specialty selected. A few medical schools offer combined undergraduate and medical school programs that last six or seven years rather than the customary eight years."
