What do you mean @VIPERastronaut ? There is no rush to accept the offer made by a university. Most give students time till 1 May to decide whether to enroll or not, even if you applied EA.
What @Banker1 is saying is that Purdue no longer has rolling admission. Meaning they take all EA applicants who submitted before 11/1 and evaluate them as 1 pool to send notices out before 1/15.
