A joyless rite of passage, the SAT is a source of dread that most adults get to ignore until they’re forced to confront it anew along with their high-school-age children. And as critics and reformers of the SAT have long pointed out, students would put down their pencils, close their booklets, exhale and instantly forget every ten-cent word and algebra formula. Indeed, the best motivation for SAT prep is that if your score is high enough to forego the dreaded retake, you can forget the whole thing ever happened.
