<p>Voodoo_Santa:
It’s actually harder to achieve 65% on an AP test as on a regular test.</p>
<p>Let’s say you get 70 questions on a regular multiple choice test and 30 questions incorrect. Usually that would translate to a 70% (unless your teacher is curving), meaning you were awarded 70% of the points available.</p>
<p>However, let’s say on the multiple choice section of an AP exam you get 70 questions correct and 30 incorrect. In this case you would be awarded 70-(30/4) points, or 62.5 points, or 62.5% of the points available. Assuming you answer all of the questions, you would need to get 76 of the questions correct in order to achieve the same score (70) on an AP exam. That guessing penalty adds up more than you would think.</p>
