<p>I want to take the Biology M subject test, but when I go to sign up for it on CollegeBoard, it keeps offering to take E/M. Do I have to take both? If not, at what point can
I choose which one to take? Thanks</p>
<p>Ok so what happens is this:</p>
<p>The format of the test is 60 General Biology questions, which include a few E & M questions. Then after that 60, there are 2 separate sections of 20 questions, one E and one M. You pick one of them while you are taking the test, and just answer that section’s questions. So basically, you don’t sign up for E or M, but you decide which one. On test day, it tells you to go to section 2 for E, or section 3 for M, and you pick one and go with it. </p>
<p>You don’t specify to Collegeboard which test section you will take, you just take it during the exam day, and they will grade it.</p>
