Regarding Purdue, here is a link to the Purdue Data Digest: https://www.purdue.edu/datadigest/. If you click on the interactive links to “Applications, Admits, and Matriculations,” and “New First-Time Beginner Profile,” you can see how your test scores and GPA compare to recent entering classes at Purdue.
I seriously doubt that you would receive any financial aid from Purdue.
