George W. Bush got a 1206 SAT, or roughly 97th percentile of the US population as a whole.
While GW is a famous ‘C’ student, John Kerry’s grades at Yale are unknown, as are his SATs. However, Kerry has released his military records and you can see his score on the Navy Officer’s Qualification test: 58 out of 115 questions correct, which maps out to roughly the 50th percentile. Although that's nothing to be ashamed of, especially considering the test is only administered to a select group of people, GW by contrast scored 67% on a roughly comparable test.
