Thank you for sharing this link which contains interesting information both within the article text and the chart titled "A Test of Knowledge or Income?" Colleges and universities may be highly interested in an internally motivated student whose SAT score exceeded scores projected (by his/her family's income range) by >500 points, at age 14? Test prep, as I understand it, was limited to the free online sample test questions provided on the SAT website.

The purpose of this post is not to extoll the virtues of the SAT, but rather to share anecdotal evidence which runs counter to the chart summary: income isn't destiny. Even without the SAT this student was similarly distinguished by interests pursued due to a sense of internal locus of control.
