Athletics and top tens

Hey CC,

I’m a strong student academically (high ACTs, taken a lot of AP classes and tests) but my GPA is somewhere around 3.7-3.8. I’m also a swimmer and I’m good enough to be in the middle of the pack at Ivy League schools, but definitely not good enough for Stanford and Berkeley. I don’t have any other ECs.

How would athletics factor into my chances for Stanford, UCs, and the Ivies? PS: I’ve just finished sophomore year.
Tyvm!
