@ suzy79 - I saw that you posted on the Yale thread asking if there is any “advantage” of applying as a computer science major. Your GPA will matter more to AOs than your AP scores, but 46% of students who took the Calc BC exam this year received scores of “5”, so your score is relatively low for a prospective CS major. If you have a good GPA of 3.85+ and high SAT or ACT scores, great letters of recommendation, essays and ECs, that might counterbalance your AP scores, but AOs at Yale and other ivy league schools will expect to see AP scores that support/correspond to your course grades. Also, I think you meant to ask if your AP scores will “affect” not “effect” your admission chances.
