Another reason GPA is problematic: it's sexist. Male students face structural barriers when it comes to college acceptance, to the point where a woman is ~50% more likely to get a college admission. Male students tend to both score higher on average on the SATs and have a higher variance. Deemphasizing SATs in favor of GPA (which itself is a discriminatory measure-- teachers systemically show bias against boys when it comes to grades, particularly boys of color) is exacerbating the structural barriers boys face when it comes to attending university.
