<p>It really depends. And yea, they’re always taught by a TA. </p>
<p>To add to the thread, google “davis open course list”, click the first link, and save that some where. It’s an extremelyy useful resource. Not only does it let you look up what’s open without having to select which departments you want to browse, but it’s more up to date than sisweb (in my opinion. I’ve heard stories of people trying to sign up for classes that sisweb said was open only to find out they’re not) It may not give you all the information you want, but it’s great for drafting schedules</p>
