I just graduated.. what an honor to have this experience. Sloan will challenge you in ways never imagined; in the end you will improve your thinking processes, become more tied to Data, modeling to achieve new ways to achieve your goals. Best of luck, enjoy the process / you will only regret it if you don't try to compete for a spot in the next cohort!
MIT Sloan seems like a school that appreciates the individual and her achievements. Not so sure if I would qualify cos it speaks of 'achievements compared to others your same age'... ah well, my MBA one day. Bucket list.
