Nothing or nobody in US. My daughter's friend was admitted by MIT at 15 and he didn't go there and studied in High School but most students didn't like him (he behaviors like a kid) and said "get out of our school and go to MIT, we don;t want you here". He went to MIT at 16 and now studies in Harvard University for Ph. D. program.
