SAT Sneak Attack: How Computer Geniuses Hack, Beat, and Cheat America's Most Feared Exam

SAT SNEAK ATTACK
How Computer Geniuses Hack, Beat and Cheat America’s Most Feared Exam
By Peter Wayner

Two students take the SAT. One uses a brain, a pencil and scratch paper. The other uses all of these, plus a dictionary, math assistant, concierge and advisor. Who wins? Today’s high school students feel the pressure to succeed on standardized tests like no other generation. In this short ebook journalist Peter Wayner uncovers how a group of elite students use tools that are allowed by the College Board, and by repurposing them, get close to that elusive perfect score.

By bending the rules these students easily beat the SAT at its own game, making the playing field unlevel. Many wonder how relevant the SATs are in the age of super-cramming and endless tutoring sessions, and this book will add fuel to that argument. SAT Sneak Attack reveals the exam’s open secret and is a must-read for those who want to know how clever computer hacks beat the test.

Standardized Tests as a Predictor of Success in College

The SAT and ACT are conventionally thought to be the most important components of a high school student's application to college. This is probably because of the fact that standardized tests are used by colleges as somewhat of a "great equalizer" among masses of high school students with very similar grades. The test provides a means to differentiate among some of these students and also gives admissions officers some idea of what a 4.0 GPA at a random school in Idaho means compared to what it means at an elite college preparatory school in Massachusetts. In other words, when admissions officers have such limited information about students and their schools, the SAT and ACT serve as extra sources of information from which to base their evaluation of applicants. And, as the former admissions officers at inGenius Prep have confirmed, the mantra "the more information, the better" is true with respect to standardized tests.

Although statistics about the strength of the SAT and ACT as predictors of college performance has been out there for awhile, the din of criticism of standardized tests has grown louder over the past few years. These studies citing the tests' predictive ability are all fairly methodologically flawed (a subject for another blog post) because of the inability to control for myriad variables; however, most people accept (not necessarily based on any empirical evidence) that higher standardized test scores reflect higher ability and will result in improved performance relative to lower scores on standardized tests.

A recent NPR article about "test-optional" schools calls this conventional wisdom into question and cites statistical evidence that students who apply to schools with "test-optional" admissions policies who choose to submit test scores only outrank those who choose not to by 0.05 GPA points. The NPR article cites this as evidence that the tests have a poor predictive ability when it comes to GPA. Yet, the tiny sample size, the bias from self-selection of people, and a variety of other factors make this data almost meaningless aside from its rhetorical appeal. The article goes one to discuss how high school GPA is a much better predictor of a student's academic performance in college (measured by GPA), which is certainly an intuitively appealing argument (and one that I happen to agree with). Nonetheless, the purported statistical evidence for the claim is too flimsy to hold up such a weighty proposition.
