A question about the CB online SAT test prep

<p>This is a question about the online SAT prep offered by the Collegeboard. The prep includes several full-length tests, 18 general lessons (some with quizzes), and 30+ additional practice quizzes. </p>

<p>My question is about the quizzes. Is there a way to use quiz results for ballparking a good or bad mastery of the topic? </p>

<p>The quizzes are generally 12 - 25 questions and scores are given as a percent, e.g., 20 out of 25 right = 80%. Simple enough. But, what does 80% mean? If it were a full SAT section, would that put the test-taker in the 400’s or the 700’s? Someplace in between? </p>

<p>Does anyone know?</p>

<p>(Yes. Son has done one full-length practice test and it provided an instant score out of 2400. He’ll do 3 more before the March 13 “real thing.” I’m just wondering if his quiz work in between indicates improvement.)</p>

<p>Thanks.</p>

<p>To a first approximation, at least on math, the raw score percentage is very similar to the scaled score percentage (offset from 200). I.e., 50% right is about 500, and 80% right is about 640-650.</p>

<p>Whether the quiz percentage is predictive of the SAT percentage and score is harder to answer, just as it is for the blue book test sections (hence the wide score ranges given in that book for a given % of questions correct).</p>

<p>I think your best bet for a predictive score would come from the two “official practice tests” from CB, since those were real SATs.</p>
