Idk what @yonceonhismouth is talking about because it literally says captain, treasurer and president- to me, that’s good enough. Over stacking on leadership positions is NOT what colleges want to see- they want to see meaningful contributions as a leader.
In terms of actual chances- I think that the fact that you’re from a “small, poor town” plays to your advantage. Maybe report your stellar AP scores to show that you’ve done well despite coming from an underprivileged background? Extracurriculars look great, I think you’ll be fine.
