How to calculate an AP exam?

<p>I took a practice mulltiple choice out of the AP Biology accompanied book to Campbell and Reece 8th edition and I’d like to know my score.</p>

<p>Out of 100 questions I got:
65 right
19 skipped
16 wrong.</p>

<p>65-16/4=61/100.
n your way to a 4-5 (borderline 5 maybe)</p>

<p>last year my teacher told me he didn’t know how they grade AP World History and that it is different every year.</p>
