Rice will likely take 1 person with your profile. AMAZING overall, but not sure how you will stack up against the other 1-2 that also apply annually. You are in a very unique category so just hard to say. Besides improving your extras, often a sore spot for homeschoolers, you need to make clear you have the social maturity to enter college at 15. In the end, that will be the determining factor among the group of talented underage applicants. Hope you get it if right for you.
