Hii.
So I self-studied for WHAP and Lang and Composition this May (my school doesn’t offer APs). I got 4’s on both, do you think that’s an acceptable score for Stanford and Yale (Those are not all my exam scores as im doing IBDP as well)
I can only give you input for Stanford. Those scores are fine. In the grand scheme of things the AP scores will play an extremely small role in whether or not you are accepted. What you have in your favor is that you self-studied for the tests. That will impress.
Stanford recommends taking a rigorous course schedule but they also make it clear they don’t hold it against students if their high school does not offer AP courses.
