May I ask where you recieved that assumption from? I have not studied much on specializing in more than one area. You may only need to complete another residency/fellowship program. However, I do know the rest of the process to a decent degree. During undergrad I will continue to keep my EC's going, as well as doing some more shadowing and volunteering. Between the summer of my soph. and junior year I will hopefully do well enough on the MCAT that I won't have to rewrite it, since doing this more than twice is not recommended. Using my MCAT scores, some schools can be thrown out of my options if it is not high enough, but this, along with my science GPA and core GPA, is what is used to apply to a medical school. The admissions comittee generally use a program that tosses out scores below a certain margin. Those that are lucky enough to pass the original dump may be called for an interview. After all of this, and possibly another interview, you may be accepted for med school. Medical school consists of two years of general medical practice and information. The following year is used to explore different specialities and the fourth year is spent focusing on one generally. During this time you must have already passed parsed the USMLE test (between soph and junior year I believe). After medical school is finished, you finish out your residency, and in the case of ID, another 2 year fellowship is needed. During your residency/fellowship, the last test for the USMLE must be passed to be come a liscensed physician. I think that is the general process at least.
