<p>For anybody that has used the Barron’s SAT Biology, 13th ed. prep book, are the score conversion methods for the 4 practice tests in the back accurate? It says to minus one for every wrong answer and the conversion chart has a raw score of -24. How can you get a -24 when there are only 80 questions?</p>
<p>LOL, one must be pretty dumb to score -24/80 when the minimum possible is -20 =P Anyway, sorry, I’ve no idea ^^</p>
<p>That’s what I’m saying, are their bonus wrong answers that you can get?</p>
<p>umm, take 1/4 of all ur wrong answers and subtract that from the total u got right.</p>
<p>I think the point here is that there are 80 questions. Say you get 0 right and 80 wrong, that’s 0-80/4 = -20. But in the score conversion chart, raw scores like -24 are listed. I’m pretty sure that’s a mistake on Barrons’ part, or it might be a way to make dumb kids feel better, since it “could’ve been worse” ;-)</p>
<p>Did some of the questions have less than 5 choices? I ask this because for the SAT II, 1 wrong for a 4 choice question = -1/3 points, 1 wrong for a 3 choice question = -1/2 point. Some of the questions on the subject tests have less than the usual 5 choices, so this may explain the -24.</p>
