The classes in medical school vary from place to place. But there
are some that everyone takes in their first two years, no matter
where they are:
Physical Diagnosis (or some kind of intro to the patient class)
The amount of lab work varies from class to class and school to
school, although some classes (like gross anatomy) feature as much
lab work as you have time for.
