I know a Colorado student on a full ride merit at UIUC. UIUC has many merit scholarships offered by specific departments that are open to OOS students. They are about has hard to win as the OOS merit at GaTech.
GaTech offers only 40 OOS merit Stamps scholars and Provost scholars get in state tuition at GaTech.
I think UIUC and GaTech are about the same for OOS merit. HARD TO WIN!
