<p>I am in AP chem and AP Bio so I'm leaning more towards molecular, but I absolutely suck at the nervous system.</p>
<p>The behavioral ecology stuff is easy to me as well as the different types of speciation (which I all assume to be emphasized on the "E" exam).</p>
<p>Which one emphasizes body systems more? Which do you think I should take?</p>
<p>I think E is generally considered easier, although its curve may be (insignificantly) tougher. I took Bio M last year, and thought the M questions ridiculously hard.</p>
<p>E has the lowest national average for any sat subject test last i heard.</p>
<p>As far as I'm concerned, both bio tests cover the same percentage of questions regarding organismal biology. I am also good in chemistry and plan to take M because it has some questions about molecular formula or enzyme catalysis or something like that and I feel I can't fail there, even if I took a practice E test yesterday and I got an 800. But if you are not decided and have time, get a glimpse to both set of questions before bubbling your option</p>
<p>D got close to 800, but when she took the practice test she missed nearly 30 questions. Not sure which book she practiced on.</p>
<p>my friend took E after taking only honors biology and got an 800</p>
<p>E is easier if you know evolutionary and ecological topics well., but if you're into biochemistry (properties of water, protein synthesis, DNA replication etc.) You'll do fine in M. It matters on what your forte is.</p>
<p>could I take Bio E this time and Bio M next time? Do colleges consider this as two tests or one?</p>
<p>Most people in my AP Bio class have said, after comparing Bio E and Bio M questions, that Bio M was the easier set. Personally I find Bio E to be easier, and the curve seems to tougher on that one as well, so look over some practice tests and see which one you are more comfortable with, i.e. which one you generally score higher on.</p>
<p>The statistics show that Bio E has the lower average than Bio M. For instance, 800 on the Bio M is usually around the 97-98% range but 800 on the Bio E is in the 99+% range (on the stats I checked). I also know that the Bio E questions are usually longer than the Bio M question, but that does not really mean much.</p>
<p>If you are in AP Chemistry and AP Biology, you would probably feel comfortable with the M. Whether you'd do better on the E is a matter of what you are better at and what your class taught. My Honors Bio class focused on molecular topics, so I took the M, but if yours had more ecology, take the E.</p>
<p>In the end, take some of the practice tests and find out which one you would do better on. Do both sets of questions and compare your scores.</p>
<p>The nervous system is not just in M--I believe it could be part of the core 60.</p>
