Can undergraduates take graduate level courses?

<p>It may be a bit late to be asking this question, but can USC undergraduates take graduate level courses? I'm taking one of USC's 400-level mathematics courses this year at home (using the same textbook), and I'll run out of undergraduate pure mathematics classes during my sophomore year. :/</p>

<p>FYI, I just submitted my application. Yay! :)</p>

<p>In general you have to set it up with your counselor and get departmental approval.</p>
