AP Testing conflicts

<p>Suppose you have two AP tests, A and B, on the same date and time. A is self-studied (and you're not TOO confident); you have taken the class for B (and are extremely confident).
Which one do you take on the late day? I could argue either way: take A on the regular day so that the curve isn't too bad, or take B on the regular day so you have more time to study for A.
What would you do???</p>
