Pretty well. I graduated in Computer Science and Physics with a first class honors degree, and the university medal (I was the top student), at 17.
I then went into Princeton to start a PhD in plasma physics -- I did that for two years but that's on hold now -- I'm starting a startup, as I guess is the ambition of many of us here.
Socially, I've always been fairly mature for my age. I got along better with college students than my age peers. It was a very good move. I hated school.
