Even for in-state residents Georgia Tech has a lower acceptance rate at 30% overall (not engineering) than Purdue OOS at well over 40% (obviously OOS GT is in a whole different realm than Purdue at a 9% acceptance rate). When you ad the competitiveness of Aerospace with Georgia Tech being ranked second behind MIT and tied for 3rd overall for engineering those numbers even go down for GT. I would definitely put Purdue as a likely with those stats. I also think this applicants stats put them in a good position at GT due to being in-state. Good luck!
