i think wellrounded is true but also, consistent activities, and leadership is part of it. son has an loa and he has average to above average stat's in comparison to what the usafa publishes with regard to grades, rank, SAT's. average cfa too! but he picked a a few activities he really liked and excelled in them over a long period of time. showed consistent and persistent interest. He also has alot of leadership in those activities. several things are outside of school - school leadership like class president tends to be more popularity driven. no one but the admissions folks really know but my advice would be to follow your passions and interests for an extended period of time instead doing an activity for 1 year and than switching to something else. Be an interesting person who excels!
