So you're saying the SAT gives a bigger advantage to people with resources to prepare, compared to a GPA which is the result of many assignments and tests across four years? That does not sound remotely plausible to me.

SAT + grades is a stronger predictor of college performance than grades alone. AFAIK this is a pretty uncontroversial finding. For a review article, see Frey (2019), "What We Know, Are Still Getting Wrong, and Have Yet to Learn about the Relationships among the SAT, Intelligence and Achievement."

Are you discounting that the factors that go I to the GPA are wildly different between schools?

I think the guy that got a 2.9 in a school that was seriously focused on education is going to be better prepared for the 4.1 from a peace and love participation trophy school.

Are you missing “standardized” portion?
