>Critics call the SAT inequitable and say high school grades are a good predictor of college success.

I mean, it seems pretty clear from the last 6 years of experience by professors and others that grades (or at least grades in isolation) aren't a good predictor at all for this. The problem is removing the use of standardized tests here was done for ideological reasons. You can already tell by the use of the word "inequitable" here, because a certain insane subset of policymakers and the public believe that we should push for equal outcomes ("equity") over equal opportunity (usually referred to as simply "equality").
