<p>If you plan on taking Bio M, do you still study everything in here? Do they only give you the option if a person feels that they have a better grasp on one or the other? Because I don't see a very defined line in the Barron's Bio E/M book for that.</p>
<p>Thanks.</p>
<p>There is a core of 60 questions that is shared between both the E and M versions of the test. It is only the last 20 questions that are different. The core includes questions about BOTH Ecology and Molecular Biology, as well as other topics, so it is important that you don’t ignore one of those sections even if you are taking the other test. By all means, focus some extra attention on Ecology if you’re taking E, or vice versa, but Barron’s doesn’t draw a specific line because all of the topics may show up on either version of the test.</p>
<p>Does that make sense and answer your question?</p>
