What's the formula for the Calc AB AP scale?

<p>I am taking a practice test from PR's Calc book, I'd liek to know how I can calculate my score to see whether I get a 3, 4 or 5.</p>

<p>i know one of you guys know it out of all you CCers.</p>

<p>the score is calculated like this:</p>

<p>raw mc score = (number correct) - 0.25 x (number incorrect)</p>

<p>raw frq score = sum of all 6 questions, each out of a max 9 points</p>

<p>overall score = 1.2 x (raw mc score) + (raw frq score)</p>

<p>the maximum score for the overall is out of 108</p>

<p>in 2002, 70-108 was a 5 for AB, and 64-108 was a 5 for BC</p>

<p>What about for a 3?</p>
