Which school if I can't get into Stanford?

It is useless to try to think too far ahead with this process. First see what happens with Stanford. If you get in, and you do have a chance, then you are done. If you don’t get into Stanford, then see where you get in, option which is best for you academically, financially, and socially. I do agree that Pepperdine doesn’t really fit with the other schools in your group. And if other Ivys appeal to you and you don’t get into Stanford, I’d put in a couple of applications to those schools.
