<p>I don't know about your personal chances, but in general Cornell is said to be the easiest of the ivies to get into for internationals who can pay.
Don't be fooled by ED numbers. A lot of ED applicants are legacies and recruited athletes, so your chances as an unhooked applicant don't necessarily improve by applying ED (they do improve significantly at UPenn though) But I hope you are not going to apply to both Dartmouth and UPenn just because they are both Ivies. The two schools are so fundamentally different that I can hardly imagine a student who would be happy at both.</p>
