Did I just mess up?

I took the SAT 4 times and my superscore is a 2360, while I took the ACT once and got a 35. Because Yale requires sending all of one or the other, I just sent the ACT. However, I forgot to take off the self-reported SAT scores off the Common App, so they’ll know I took it but didn’t send it in… is this bad?

No. You’re required to send in one or the other. You sent one, and the self-reported scores on the other are clearly nothing to be ashamed of. If you don’t get in (and these days 94% of applicants don’t) that won’t be the reason.

@DeepBlue86 Thank you!
