<p>yes, your pass I only lasts 4 hours, but i believe as long as it’s after 8 PM on the days FOLLOWING your pass time, you can rearrange your schedule. :]</p>
<p>for example, if i had my pass today (and missed my appt.), i could register for classes right now because it’s now after 8 PM. if i wanted to rearrange my schedule, i could do so as well.</p>
