> This is ironic because in the U.S. most people believe the S.A.T. is the most biased portion of the college entrance criteria.
I don't see any evidence either that most people believe that or that it's true.
I personally find it more likely that high school grades and extracurriculars are probably the most biased portions (grades because a large portion of them usually depends on assignments with loose grading rubrics, which are empirically linked to greater racial and other bias for otherwise similar responses, and extracurriculars because both access and evaluation of them is impacted by cultural factors of both the student, the evaluators, and other members of society.
