What do you call a person that got a D- in medical school**********

DOCTOR [/QUOTE]

Actually, it is "what do you call the person who graduates at the bottom of his or her medical school class"

But here's another one for thought in the context of this thread.

"What becomes of a medical doctor who fails to get board certified?"

He will likely find something, but he will be excluded from many practice opportunites and will be denied hospital privileges at most hospitals throughout the country.
