UC Irvine - COSMOS 2020

Hi guys! I am a current high-school sophomore applying to the COSMOS summer program 2020 at UC Irvine for cluster 5 and cluster 2. What are my chances of getting in with these stats?
GPA: 3.71 UW/4.29 W
E.C.s: Science Olympiad 2 years, Debate 3 years, Stem Girls 1 year, Cross Country 4 years, soccer 2 years
Won awards at two debate tournaments, one at science olympiad tournament
Taking AP Calculus AB, Honors Chemistry
I am a bit worried since my GPA is low, so I am a bit curious about what my personal statement should be about. I am having a bit of trouble getting started on writing it.

Hey I’m also applying to UCI COSMOS but not those clusters, your STEM a extracurricular activities are great. I think your personal statements should really focus on how passionate you are about those certain clusters.
