Some of the scholarships in the Automatic Full Tuition thread are only for students who enter directly from high school. But some are also open to students who have taken a gap year. Work your way carefully through that thread and see which scholarships are still available and what is required. Also, spend some time in the Financial Aid Forum reading up on the topic of merit-based aid, and post your own questions there. You will get some good ideas. Watch for anything by @mom2collegekids She is one of our merit-aid and pre-med experts.
Wishing you all the best!
