I have a 3.3 GPA Does anyone know what the SAT correlation should be?

I got a 1980 on my SAT is that average for my GPA? I always complain about how my school is so hard and how I wouldve been able to get a much higher GPA and gotten into BC(my ultimate dream school) if I had gone to public school but maybe I'm just stupid and a 3.3 is all I can get. Just curious what the GPA to SAT correlation should be
