<p>“Undergraduate students who register for more than 17 credit hours are charged the flat full-time tuition rate with an additional charge for each credit hour over 17.”</p>
<p>I took 18 credits a couple of times in order to graduate early. If taking normal 3 credit classes, that is 6 a semester. It is doable, but expensive and difficult with an internship. </p>
<p>On the contrary, if you take 17 or 18 credits you are maximizing your dollar per credit average as you pay a flat fee for semester tuition. 18 credits would mean you would only pay for one credit or roughly $1000 - $1500(whatever AU’s high tuition rate is these days); but that’s a heck of a lot better than an extra semester of tuition or a summer course($3000 +)</p>
