I think she’ll get into Pitt and UMass, and that’s two great choices already. Since she prefers big schools, the list that @tsbna44 gave you is so helpful plus those thoughts on schools in the south.
If she’d like another target, I think she’d have a chance at Penn State if she applies by 11/1. Just an FYI, their alumni group runs charter busses between Penn State and and MA & CT every break so you wouldn’t have to go down and get her/bring her back for Thanksgiving, winter break, and spring break. It’s a great little perk.
