Tuition- Do we pay per class or quarter?

<p>Just wondering, how is the billing of a quarter? Will I pay more if I take 4 classes a quarter versus 3? I might want to make up one of my arts requirements in ERC at a community college over the summer.</p>

<p>Thanks in advanced</p>

<p>(no "d" in "thanks in advance")</p>

<p>UCSD doesn't charge by units. take as many as you want, but units beyond 22 will require petitioning.</p>
