My Son Will Graduate High School at 14 - Which of the 3 Big Schools Would Be Best?

[rebel100]

In that case, I think you're making a mistake sending him to one of the big 3. Get him set to take the next SAT/ACT exams and help him assemble admission portfolios. Start calling around to adcoms and explain your unique situation. AP exams are coming up, he can start studying NOW and he can likely earn a much better chance for admissions bringing in AP credit.
His unique situation might allow him to get a full scholarship, and if he is extraordinary, it's going to be lost on a degree from TESC. The big 3 meet a need, but it's not to launch a brilliant young person to greatness. TESC is not the path into a traditional PhD program. He can (and should) take no less than 5 AP exams (especially Latin since so few do) and perhaps a few CLEPs in the maths. Solid scores will fast forward him through his first year of college and he'll start as a sophomore. If he takes 15 credits per semester instead of 12, he'll be out in 2 years and likely a ROCK STAR candidate for a PhD program.

All the best to him!
