I would think coming from Hawaii ought to help you. Doing well in the AP classes and on the AP tests will help, along with great extracurriculars.
Purdue requires three years of social studies, by the way. Thought I would mention it. My DD wants to study CS, and if she wants to keep Purdue on her list, she is going to have to revamp her plan, which currently only has two years of SS. Many selective schools recommend more, but only require two. Purdue is one of the few that requires three.
