<p>alrighty. how is this done before class actually starts?</p>
<p>switching professors? You have to drop the class & then add the class taught by the other one. But since other people have already registered, etc... you may end up waitlisted. Switching sections is risky.</p>
<p>argh. so the system won't allow me to keep my current section while attempting to enroll in another?</p>
<p>Not for the same course, no.</p>
