Here is another thread about large merit aid for stats (test score and gpa) http://talk.qa.collegeconfidential.com/financial-aid-scholarships/2006094-2017-automatic-full-tuition-full-ride-scholarships.html
I would caution you not to start at a community college during a gap year if you intend to pursue large merit. Earning credits can change your status from incoming freshman (which have the best opportunities to win merit) to a transfer applicant (generally fewer scholarships, if any are offered by schools).
