<p>All great advice posted above. I would echo what Donemom said, look into Stanford's EPGY program along with all the other programs mentioned. My son has taken a few of the courses and has his own math program laid out for senior year at his high school.</p>
<p>Additionally, the Harvard Extension school has a few online classes.</p>
<p>Something I have noticed this year about high school and the college applications is that a number of schools have a question on their application asking whether you graduated from high school. I think that allows some students to go directly into college.</p>
<p>One last thing, because it has not been brought up by others, is the University of Southern California's Residential Honors Program. They accept students after their junior year in high school, have separate dorms on campus for the students. They also get to take college level classes if appropriate. Go to the USC website and do a search for "Residential Honors Program" for more information.</p>
