The early results of The Washington Post’s SAT quiz — including sample questions from the College Board’s revamped SAT — are in, and it’s clear from the numbers that those who took the test are more astute at reading than they are at math.

More than 2,100 people completed the quiz as of 2 p.m. on Wednesday, with tens of thousands more clicking on the quiz and checking it out but not hitting the “finish” button. There wasn’t a single question that everyone answered correctly, but two of the reading questions received correct responses more than 90 percent of the time (93 percent of respondents got No. 2 correct; 96 percent of respondents got No. 9 correct). All but two reading questions drew correct answers at least 70 percent of the time.

Math was a different story. Six of the 12 questions had correct answers from fewer than two-thirds of respondents. One math question proved particularly difficult, with just 42 percent of respondents answering correctly. That question, No. 17, came from the “passport to advanced math” portion of the sample questions the College Board released Wednesday, and it focused on polynomial functions and algebraic representations of polynomials. Here’s that question:

Question17

The answer, according to the College Board, is “-18″. Here’s the explanation for how a student could get to that answer:


As of 2 p.m., 52 respondents — about 2 percent — had perfect scores (21 of 21 correct on the quiz). But it’s impossible to know whether those people actually aced the quiz or, well, figured out other ways to enter all the answers correctly.
