Matching a HS Junior with 3.7 GPA, 31 ACT

I agree with the above posters regarding Purdue being a reach for OOS engineering students. Looking at the Purdue Data Digest, here, https://www.purdue.edu/datadigest/, may be helpful in this regard: the Data Digest, under the links for “Admission, Admits, Matriculations” and “New First-Time Beginner Profile” give information in an interactive format on test scores, GPAs, etc. based on different types of student parameters. You should be able to compare your statistics with those of entering freshmen from recent years.
