<p>I’m not so sure practice tests are a good estimate. On Barron’s, which is supposedly the hardest book with exams that are way harder than the real test, I actually got a 790 of my first Bio M and a 760 on my second bio M.</p>
<p>The real thing today seemed for more challenging. I left 7 blank and I guessed on a bunch, which I suspect will get me an even lower score.</p>
<p>As for the Bio E curve, it depends. Although it’s generally known that the E curve tends to be better than the M one. My Barron’s practice tests say that you can miss 3 questions and still have 800.</p>
