<“I’ve heard that in USA, minority + legacy + VIP (donors) + VIP (children of politicians) + recruited athletes + low SES take, approximately 60% of slots.”
It is nothing short of bizarre that you assume minorities, legacies, athletes, and low SES kids must not qualify academically.>
If all these students are qualified, they would not need special hooks to get them in. Admitted due to a Hook = less qualified than the rest of the admitted applicants.
BTW, why do you left out VIP (donors) + VIP (children of politicians) from your response?
