<p>I'm getting varying opinions on both tests. Can someone clarify?</p>
<ol>
<li><p>Which curve is greater, E or M? How big is it?</p></li>
<li><p>Barrons seems pretty hard, but PR is easier. Which one is correct?</p></li>
</ol>
<p>Please help?</p>

<li><p>Yes Biology M has a greater curve (but varies from year to year) normally it has a larger curve by about 3 points. If you are a strong student and typically do well on tests the Biology M is the test to take. If you are a mediocre student then taking the Biology E test is better because the questions are easier.</p></li>
<li><p>I personally prefer Barrons because they give good information and details that come in handy for the test.</p></li>
