As far as I know, IU mainly looks at GPA and SAT/ACT. With a 3.0 and a 30 ACT you should be admitted whether you are in state or OOS. However, you will not be admitted directly to Kelley with those stats (GPA too low), so your goal will be to do a great job your freshman year at IU and apply for standard admission to Kelley for your sophomore year. I think IU only looks at criteria other than GPA and SAT/ACT if you are borderline or have a special hook. I wonder if they even look at the essays and extracurriculars or in state vs OOS if your stats are not borderline.
