Cost per credit if you take >18 credits?

<p>I was wondering what, if anything, it costs to take more than 18 credits in a quarter?</p>

<p>From what I remember, a full time student is paying enough tuition for 12-20 credit hours.</p>

<p>Taking more than 20 hours, in addition to being expensive, is also pretty much crazy, so that doesn’t really matter.</p>
