<p>I think just about all colleges flat out deny certain homeschoolers acceptance 
PM me if you want contact info for a friend of mine who was homeschooled and ended up with several extremely good options for college; she’d probably have useful perspective on the process of applying as a homeschooler if there’s no one here who’s had that experience. (On the other hand you probably know of a lot of other homeschooled students, and obviously you’re looking for information specifically about Caltech.)</p>
