Graduate early?
JimmyL: As many have said, he socialization of high school is worth it. I'd even go as far to say that what you would gain by moving everything forwards a year would be less that what you'd gain by having a more "normal" college experience by coming in at the right age, but I have no numbers for that.If you're bored, start contributing to Open Source stuff (maybe turn it into an Independent Study course), do a start-up (look at Mark Bao to see that it's possible), and study a bit so that you can destroy your SATs. You may as well take a few more APs too - figure out which ones will transfer well to you college (as I left HS with six APs, but only got college credit for two of them since they most were in random things like European History) and do them; things like Computer Science AB, Physics C, Calculus BC, and Chemistry should let you bypass almost all of your standard freshman science courses, and will be much easier than their corresponding "real" college versions.If you really feel like you need some knowledge, follow along with an MIT OCW course (and if you're really ambitious, find a teacher who will let you do an Independent Study on it) or an evening one at your local community college.I'd also suggest finding an interesting teacher to hang out with and establish as a mentor. In my junior year I took Comp Sci A, as taught by the school's director of IT. He knew I would get a five in a heartbeat (and I did), so he suggested some other projects which were pretty cool. The following year I couldn't take BC based on the schedule, but I would drop into his office every other week or so to hang out, talk about what stuff I'd been working on independently. More often than not we'd start digging into some code and two hours would have passed before I'd leave, at which point I'd go back to whatever class I was supposed to be in (armed with a good excuse note). As a rsult of this I polished my skills, got access to a whole lot of the school, and got some really good advice about how to succeed in the business. I still talk to that teacher, ten years later.Most important, thought, is enjoy yourself. Hang out with your friends, pick up some hobbies, hook up in the park, steal your parents' booze, make fixable mistakes. You will never be a kid again, and the marginal value of one more year of "real life" isn't much.
