Is U Chicago affordable or would you be reliant on aid?
You might call USC anonymously and find out the odds of achieving an award.
You’re not the first in this situation.
Maybe they can let you know if it’s worth your while to move off U Chicago. If 10% earn the full tuition, then maybe it’s not worth the risk.
Also, ask your family - they may say - stick with Chicago, we’re willing to pay.
This is one of those - I say kiddingly - you hope you get rejected - just so it makes your SC decision easier…but I know, Chicago is your tops. And that matters!!
You win no matter what you choose - both are fantastic.
Best of luck.
