If you applied RD to Purdue, that lessens your likelihood of admission as they fill most of their class EA. And, the average ACT score for engineering is a 33.
Kudos for having the UCF full ride under your belt!
For others reading this thread, OOS acceptance rates to flagships is less than what is published by the university as a whole. For engineering or CS, the acceptance rates are even more competitive. GT, UNC, Purdue, etc…are not safeties or matches.
