<p>Ah, my school had a similar situation. Here's what happened: </p>
<p>People in my school were taking the AP Chemistry test. The fire alarm went off, and they were forced to evacuate. Whatever time was left was added when they came back. </p>
<p>I'm sure it'd be a similar situation. If not, late testing might be available if the counselor recommends it (I think? Maybe not.)</p>
