What year are you now in high school? Will you be an in-state or OOS applicant? What would be your intended major and/or to what college would you be applying? Also, being a minority may or may not help; the real issue is whether you are an underrepresented minority (“URM” in admissions parlance).
Here is a link to the Purdue Data Digest, here, https://www.purdue.edu/datadigest/, under the link for “Applications, Admits, and Matriculations”. It is interactive, so you can input the parameters that most apply to you. Based on your input, the Data Digest will generate information and create some graphs/charts from which you may be able to make an estimate of your chances. Also, there should be a table at the bottom which gives the admission rates (and yield) for students matriculating in the Fall semesters of the past 10 years.
You can also look at Purdue’s Common Data Set, here, https://www.purdue.edu/oirae/resources.html. Part C7 tells you what admissions factors Purdue considers to be “very important,” “important,” “considered,” and “not considered”; Part C9 of the CDS gives the median 50% for both SAT and ACT scores, as well as the percentage of the entering first-year class falling within certain ranges of SAT and ACT scores.
I don’t know whether your high school has Naviance or any similar program that gives information about how students at your high school have done in applying to colleges and universities; if so, you might peruse that data for applicants to Purdue from your school. I would also try to meet with a guidance counselor at your high school early in the Fall semester of your senior year (or if you are a junior now, perhaps you can squeeze in a meeting before the end of this academic year), in order to discuss application strategies for Purdue. If any former students from your school have been admitted to Purdue recently, the guidance counselor may be able to give some insight into how and why such student(s) were successful.
