School is too easy for me?

Well, you might want to talk to your high-school counselor to try to get you involved in something that challenges you. I think that's the problem. Do you have Science Olympiad, or an extracurricular activity that would challenge you? I wouldn't recommend home schooling if you even want to consider college, though, as a high school degree is VERY different from a home-school degree. Also consider PSEO (Post-secondary enrollment option) if your school has it. Fortunately, if you do want to go to college, you'll be as challenged as you want to be.
