University of Cincinnati, advice for a high school senior?

I’m going into my senior year of high school. I have killer extra curriculars, 100+ hours, 26 ACT 19 Writing, the only thing is that I’m going into my senior year with a 2.6 GPA. I’ve struggled with drug addicted parents my whole life but I’ve tried and getting to college is all I care about. This is my dream school.

Anywho, should I apply early action? Or wait it out? And any other advice would help too!

Thanks
