U of Michigan -uwGPA ?

I came across references of U of Michigan’s uwGPA and that Michigan treats A- as A, but does anyone know whether it only calculates core courses? I assume it won’t include PE or chorus in the calculation, but does Michigan include computer science or Psychology?

It said ALL classes.
