Look at the Data Digest, https://www.purdue.edu/datadigest/; it may give you a historical perspective on how you compare to other applicants for the college to which you are applying.
Also, Purdue’s Common Data Set, see https://www.purdue.edu/oirae/resources.html, can provide statistical information at Part C that may be useful in helping you gauge your chances. It will also tell you, under Part C7, what factors are “very important,” “important,” “considered,” and “not considered” in admissions decisions.
I hope that your spelling in your application essays is better than what we are seeing here, or your GPA and test scores may be irrelevant.
