Just know what your in for. Schools want:
Diversity, kids who they feel they can “save”, strong grades, and full pay.
Unless your kid is true stud which there are 4-5 per year, you are looking at a minimum of 18k per year.
The average size, above average student and athlete from a blue collar family is getting 40-50k, but your still on the hook for 15-25k.
Study the ssat, play an instrument or sing, do something that makes your profile different then the other 800 kids applying. Good luck!
