<p>How accurate is the prediction? It looks so lenient for AP Bio.</p>
<p>my thoughts exactly, the calculator weights the MC at .9 while my princeton review book weights it at .75, There seems to be no definitive answer to which weighting is correct, to be safe just assume it is .75 and that for a five one needs like an 86, that way you should be good to go.</p>
<p>The multiple choice is worth 90 composite points (60%) and each FR is worth 15 composite points (10% each). MC raw score is multiplied by .9 (since there are 100 questions) and the FR raw points are multiplied by 1.5.</p>
<p>A 5 is generally around 95 composite points and a 4 around 77 according to Crash Course.</p>
