Easy to change discussion?

<p>I just got into one of my waitlisted classes but the discussion period is at 8:00pm to 8:50pm! Normally this would be fine but I believe this clashes with the fencing practice schedule at UCSD and I won't be sure about whether or not I have this particular time commitment until school starts. </p>

<p>Are discussion periods easy to change during the school year? Or should I just try to get into another waitlisted discussion right now?</p>
