Several posters think there ought to be harder tests with higher ceilings for college admissions. I'd like to see that too, although it should be noted that the vast majority of colleges are not that selective, and for them the SAT and ACT work fine.

The American Physical Society, the professional organization of American physicists, has published an opinion piece saying that the math section of the GRE general exam (which does not cover more advanced math than the math section of the SAT) is hurting the quest for diversity in U.S. physics PhD programs:

Admissions Criteria and Diversity in Graduate School

If there is no consensus that the math section of the GRE general test is too easy for prospective physicists, agreement that the math section of the SAT is too easy for selective college admissions is unlikely.
