IQ score: 148.8

President No. 42 (1993-2001) had a very hectic childhood amid a lot of family drama, but he didn’t let that hold him back.

Clinton established himself as a strong student in high school, which led to an opportunity to represent his school and meet JFK — a meeting that inspired him to enter public service.

The young man banked on scholarships to fund his education at Georgetown, then at Oxford, and finally at Yale Law School.

After teaching law at the University of Arkansas, Clinton was elected Arkansas' governor. From there, he worked his way up to the nation's top office.
