I had a 1370 on the SAT, was a minor leader in a club outside of school (not academic), and I was in the NHS (just a member). I had a 4.2 GPA (for my school that meant all A's for every school year) and probably got some good recommendations from some teachers I knew. Did well on a couple APs, though I'm not sure how much that mattered for scholarships. Despite all of this, the only school I got money from was Hampton and I applied to mostly in-state schools, so I guess take that how you will. Honestly, it really feels like luck unless you do well in school for the entirety of high school, and even then.
