How hard is it to get into Cornell?
The percent of applicants admitted is 18%. You need a SAT Critical Reading score of 640-730, SAT Math score of 670-770, and/or an ACT Composite score of 29-33.
Unless you wish to apply to more than one of Cornell's seven undergraduate schools, their admissions decisions are completely independent of each other's. General admissions statistics from the university are published online (http://dpb.cornell.edu/documents/1000001.pdf), but speaking with the admissions offices of the individual colleges is probably the best way to figure out how you'll match up against other applicants. It also shows your interest in the college, which can only help your application.
