flyfishpj,
My son doesn't visit the forum but I can give you his stats.
He has received 4 year AROTC scholarship offers from every college he has applied to. (Obviously wants Army). I don't know how their requirements match up against NROTC. I can give you his stats, extra curriculars, etc.
GPA 3.8 (unweighted), 2080 SAT'S, 2 AP classes per semester since Grade 11, the rest mostly honors. He has 6 years of Spanish and 2 years of French. Extra curricular activities include 4 years of outdoor track, 2 years of indoor track including a trip to States for shot put, Student Senate grades 9-12 and Student Senate Treasurer-Grade 12, Nat. Honor Society, Distinguished State Scholar, AP Scholar, volunteer Spanish interpreter for local health clinic, Boys State 2006, Boy Scouts, took a college course over summer between junior and senior year (received an A in course) and worked full time as a computer technician for a local college for last two summers, works 15-20 hours per week during the school year at a local grocery store.
One of the colleges that offered him a scholarship is an Ivy League college. AROTC is his back up if he doesn't get his appointment to USMA.
I hope this information helps you and best of luck with your plans.
