<p>Hi, I'm a freshman who just returned from the orientation. Just checking: We are allowed to drop a class that we enrolled at the orientation and add another one, right? That's why we have access to URSA?</p>
<p>You can change all you want, although it's not a great idea because the later you wait, the harder it will be to get classes (that is if they are the ones that people are likely to sign up for during their orientations in the coming weeks).</p>
