I was in your exact same boat, though I stopped just shy of multivariate calculus in High School, and after the first 2 calc classes, took statistics and whatnot.
Anyway, I would suggest staying in high school and enjoying it. I ended up only going to school for half the day my senior year along with a buddy who was in a similar situation. Then a few days a week, we'd attend a college class in town. The other days, we'd go to the beach, or really anywhere and just relax. Those are days we'll never get back, but it's ok, because I think we spent them properly the first time around :-)

College will still be there in a year.
