If this is a college scholarship that you are looking for, do you know where you will be attending college next year? Have you spoken with the financial aid office there?
Unfortunately, beyond going to normal route of scholarship search services and the financial aid office, I don't know of any scholarships specifically for accelerated students. Maybe you could try for a Mensa Foundation scholarship (they aren't big) or other scholarships that target or are offered by organizations for gifted people.
