<p>While looking at the class schedule, sometimes there are discussion sections/classes with almost no one signed up for them. Especially with the discussion sections, other time periods may be full or at least have a lot of spaces full.</p>
<p>In one particular case, a really empty class (4 seats taken in a class of 27) fits my schedule better. Do sections like this end up being cancelled, forcing me to pick another time later? Or will it eventually fill up with students?</p>
