Chances USD Regular Decision

What are my chances of getting accepted RD?

ACT-32
Gpa-99/100
Extra Curriculars: horse back riding, basketball (not on school team), some volunteering, summer job, equestrian club sophomore year
3AP classes this year, some honors classes other years

I’m a little worried because for my second marking period, I have a risk of getting a C. I’m not sure if that would hurt my chances, but I want to know. Also, does USD require a mid year report? Thanks!

The C is in AP Calc
