AP Bio free response-how do they grade it?

<p>How many points can you get total from one free response portion of one test? How many points per question (Does that depend on the question, or can you assume there's a max of 10?) </p>

<p>Also, what percent of the free response test should you get right to get a 5? </p>

<p>I'm completely confused as to what kind of score I'm getting on these practice tests... any ideas?</p>

<p>Multiple choice is worth 60% of grade and essays are 40%; each essay is ten points</p>
