scoring for ap calc ab/apush/apwh

<p>hi - does anyone know what percentage of questions one needs to get right on the multiple choice to be on pace for a 5 on 1. ap calc ab, 2. apush, and 3. apwh? the free response questions obviously carry great weight as well, but i want to know how i'm doing with my princeton review practice tests (as far as the mc goes). thanks!</p>

<p>I've heard that it's around 75% for Calc AB</p>

<p>shouldn't it tell you in the front of the PR book?</p>
