<p>Very few colleges flat out reject homeschoolers these days. Some do have additional requirements, usually additional SAT II exams. Your best bet is to call the college admissions offices and ask if they need anything extra from homeschooled students. I specifically recommend calling rather than e-mailing because it’s much easier to discuss particulars of your situation on the phone rather than via e-mail. </p>
<p>Caltech does not have additional requirements for homeschoolers. I know they’ve accepted homeschoolers in each of the last three years.</p>
