<p>What are the general mean composite scores needed for a 5 on the AP Physics C: Mechanics test. Does anybody have any of those statistics and how much are each multiple choice and free-response worth? </p>
<p>What are the topics from that exam that need the most prep time?</p>
<p>I believe there are typically 90 points, 45 of which are free response. There are 35 MC questions, and the formula for MC score is something like (right - .25<em>wrong)</em>1.28something. My teacher told us that the 98 exam needed a score of 55 or better for a 5.</p>
