<p>Is the AP exam more difficult than the SAT subject counterpart. So if I studied for the AP biology exam, i shouldn't have a problem with the SAT biology test?</p>
<p>The answer differs based on how you define difficult. It's harder to get an 800 than a 5. Given that the AP book and SAT book cover different things, restudy.</p>
<p>Strictly speaking from percentiles, a 5 would be equivalent to approximately the 690-800 range for the Bio-E and 720-800 for the Bio-M.</p>
