Where did FDR go to high school?

FDR attended Groton School for boys in Groton, MA. He entered the 1st Form at age 14 after being schooled at home by tutors and governesses. That was two years after he should have. Normally, boys entered GS at age 12 years. His grades were not much better than a "gentlemanly" C. In 1900 he entered Harvard, graduating in three years with a degree in History. After spending an extra year at Harvard to continue editiing the Harvard Crimson he entered Columbia University to study the Law. He did not finish his degree at Columbia, but went on to take the Bar Exam and passed.
