<p>Okay, I'm registering right now (and am, obviously, a procrastinator) for bio and it just says Bio E/M - however, I want to take the molecular. When do I indicate that? On test day?</p>
<p>Yeah it's just a little box you indicate Biology-E or Biology-M;</p>
<p>and then u fill out a code for bio E or M.</p>
<p>Wait, when is this? When registering?</p>
<p>no, you decide on the day of the test</p>
