MIT and Cornell do not give merit awards at all. BU gives some based on the strength of your application…but not guaranteed. You would need to apply separately for more generous BU scholarships.
University of Chicago and Rice give very few merit awards…mostly need based.
For the others…are you in state residents for any?
And for ALL application information will be found on their websites. I will say…keep a very close watch on DEADLINES for both admissions and scholarship applications. At some places your application for admission is also required to be submitted early. Separate scholarship applications are usually due before December 1…YMMV by school.
Also, how much merit aid do you need? and what are your student’s stats? How much can you pay annually for your child to attend college?
