Would I still be considered in Yale/Harvard/UPenn?

Ivy League schools accept over 40% of students with alumni connections...because of your alumni connections an SAT score of over 2000 will pretty much guarantee your acceptance. Don't forget to do 3 SAT subject tests (high 600s or low 700s should work for legacy applicants)...If you can do that you are almost certain to get in ;). Good Luck
