<p>Is it possible to change discussion/lab sections if the class is full?</p>
<p>Depends on the class. The lower divs (Chem1A, Physics, etc) usually announce a “swap meet” of sorts where lists are established of people who release 1) what time they currently are enrolled in and 2) what time they’d like to have, and if anyone else find that fitting for them, the two of them will simply switch.</p>
<p>When does the swap meet begin? most likely before the semester starts?</p>
<p>No, definitely after the semester starts. Usually the professor will announce it on the first day of class.</p>
