<p>So what exactly IS drop/add? I noticed today that I'm still allowed into the registration system (I'm a rising sophomore). Is drop/add just when they purge the waitlists and make it so that everybody who adjusts their schedules has to add or drop a class (ie nobody can waitlist a class anymore)?</p>
<p>More importantly, can I switch around my schedule right now, if I want to? There's a spot open in a class I want (not a waitlist spot, an actual spot), so I was wondering if I could just snatch it right now instead of waiting for drop/add...</p>
