GPA seems much more likely to be entangled with various aspects of privilege than SAT. For instance, I attended a HS where GPA was graded on a 4.0 scale, even for advanced placement and college credit classes. The consequence is that you had a bunch of "Valedictorians" with perfect GPAs that attended spitwad classes. Other schools I've seen grade on a 5.0 (or even a 6.0 I believe) system, to differentiate. I would also suspect that GPA is more easily influenced by parental involvement than SAT (or just a plain IQ test).
