<p>Which one is easier/have a better curve? What material do I need to know for each?</p>
<p>I took Bio E first and then about 5 months later took Bio M. I did better on Bio M..but had a higher percentile in Bio E..
So I guess in Bio M you can have a lower percentile and still get a higher score. Don't know if that quite makes sense or how helpful it is...but I guess it's something to consider when making your choice.</p>
<p>if u have enough time, just look at both sets of questions, then pick the easier set, on the spot. You're allowed to do that.</p>
<p>For me, E is consistently easier (on practice tests and stuff), but on the day of the test, I actually picked M based on what i saw. I only took the test once.</p>
<p>the curves aren't different by much, one question difference at most, if even that.</p>
