Graduate early?
David: As a high school senior, I'm jealous of your opportunity (though no doubt you earned it.)
I would probably leap at the opportunity to skip this year.
I share your opinion on wasted time, but more with classes I don't feel that I need than with other students who hold me back.Part of my distress is my graduating class of 46 people. I don't have peers, and it pisses me off sometimes. But that may not be the case for you.
If I had a group of like-minded, intelligent, and ambitious people to hang out with, I would probably be looking forward to this year.And surely there's something to be said for learning how to do things before you're expected to do them right... I think, in my case, that's especially true of relationships. I need this year for social development, even if my intellectual development will suffer a little.You, however, would appear to be more motivated than I am. If you can seek out a college course load in high school, in whatever area you're interested in (that is, without too many fluff courses), then gaining the extra year of social development would likely be beneficial in the long run --  no downside.Putting myself in your situation, I would want to skip the year. What I should do, however, is NOT skip the year.
(I had a similar debate about skipping 2nd grade, except that I didn't really know how to weigh the possibilities back then. (I didn't go for it.))As tsally suggested, I would definitely try and find a college professor to work with. Do research in your field of choice. It's more interesting than lit homework, neh?So I'm not really sure why I would be qualified to give you advice. Feel free to ignore. =)
