I think your chances are good, because your test score is close to the threshold of 1370, and your wGPA well over the required 3.8 (have your HS send your transcript with wGPA).
I would apply soon, and as soon as your IU computing account is up and running, complete the petition, according to the instructions. Do a good job on the extra personal statement that you have to complete for the petition as well. https://kelley.iu.edu/programs/undergrad/admissions/future-freshman.cshtml
Good luck.
