What are my chances for Cal Poly SLO?

I’m currently a senior with a 4.0 unweighted and a 4.5 weighted GPA. My SAT score isn’t so great at 1200, but my ACT score is a 28. I have taken every AP class my school offers, which isn’t a lot since I come from a small town in Northern California. I plan on applying to Cal Poly aiming for a biology degree and I wanted to know what my chances of getting in are.

CP uses 9th-11th grades for the a-g course requirements and caps the weighted courses at 8 semesters for 10-11th to get their GPA.

Use this calculator but include 9th grades to get your weighted CP GPA.
