You would need to apply to the colleges.
You can find a lot of good information on school specific scholarships in this section of CC: http://talk.collegeconfidential.com/financial-aid-scholarships/1678964-links-to-popular-threads-on-scholarships-and-lower-cost-colleges.html#latest
BobWallace actually has an ah-mazing list for automatic full tuition scholarships for different combinations of SAT/ACT & GPA: http://automaticfulltuition.yolasite.com/
