SSAT scores as a method of BS selection

This one line, in particular, is very interesting: “One of the most compelling pieces of data was the strong performance of students whose families needed $0 – $9,999 to bridge the affordability gap. This group outperformed all other categories of students in terms of grades and SAT scores.”

I think that this speaks to the fact that no matter how hard a school tries, true meritocracy is difficult to obtain. Full pay kids have a higher acceptance rate and lower scores (despite special SSAT tutors and classes) compared to full FA kids, yet, get better grades and SAT scores 4 years later? There must be something about having access to additional resources that allows for this higher level of achievement in this group.
