How does the Biology E and M work?

<p>Do you select one of the two on the day of the test?
I am not sure how this works</p>

<p>You select one on the answer sheet. M is more memorization while E is more reasoning. Mostly the same.</p>

<p>Yep, you get a choice between which one you want to take. I found the Biology M to be easier, but it is different for every person. Take a practice test and see which one (E or M) you like better!</p>
