@BobWallace Thank you for the link! It was helpful.
Thanks to all who replied and thanks for the clarification that corporate/college/one-time NM scholars are all considered scholars. For some odd reason my school does not seem to think that way. We have had students in the past receive college-sponsored NM awards but my school maintains that “nobody here has ever won the NM scholarship before.”
So it looks like SAT > PSAT for NM scholarship consideration. As for EC’s I’m just glad there doesn’t seem to be as much emphasis placed on extraordinarily unique EC’s as in admissions to elite schools.
