<p>So I took the bio test awhile back and thought beforehand that taking the ecology section rather than molecular would give me a higher score. However, I scored in the same percentile as a friend who took Bio-M but he scored 40 points higher. Is the curve always for Bio-M then(I plan on retaking it)?</p>
<p>Biology E: 80 questions
-3: 800
-4: 790
-5/-6: 780
-7/-8: 770
-9: 760
-10/-11: 750
-12: 740
-13/-14: 730
-15/-16: 720
-17/-18: 710
-19/-20: 700</p>
<p>Biology M: 80 questions
[A little bit more lenient than E, but around the same. -20= 700, -3= 800]</p>
