I agree that scholarship vs non-scholarship doesn't matter, except that the scholarship people can benefit from more personal attention from cadre and MS professors because scholarship cadets have more defined goals to meet in order to keep the scholarship.
DS's roommate is on 4-year scholarship and gets pulled by cadre to do more intense runs and more intense workouts than the other guys in his company.
The non-scholarship cadet, however, can get just as far on his own if he puts his mind to it. Who's pushing you to work harder? Push yourself.
