<p>You have slightly lower chance then the top qualified. Grades to low for princeton, stanford, Cornell, columbia, Brown (reaches). Duke would be a low reach. UM, Upenn, UC are a little above but you could be surprised. OSU, UW, UN matches. do you have any safeties (unless one is your state school).
Chance me plz!</p>
