You need to consider a couple of things when looking at public flagships - the acceptance rate for OOS applicants and the acceptance rate for your intended major. Overall acceptance rate is meaningless.
And being “confident” doesn’t make a school a safety or match.
For example, IU Kelley has one of the top undergrad business programs. The average GPA for Kelley is a 3.9, and that includes instate applicants. You will need to reach the 3.8 GPA benchmark to be even considered for their direct admit program. (3.8 GPA/1370 SAT is the minimum to be considered). That makes it decidedly NOT a safety for you at this time.
