Since Purdue is on your list, you might look at the Purdue Data Digest, here: https://www.purdue.edu/datadigest/; and especially the links to “Applications, Admits, and Matriculations” and “New First-Time Beginner Profile”. You can plug in your stats to some of the interactive links on these sites, and perhaps get an idea where you might fall relative to recently admitted OOS applicants to Purdue.
Computer science may be a hard row to hoe for admission at Purdue.
