<p>You can’t take 16 credits in the summer. You are limited to 8 credits, I believe. And then you have to pay for housing.</p>
<p>However, I do know some people who have paid upwards of $8,000 for one summer and knocked out a whole semester (saving 25K, tuition + room and board). They only took 8 credits, but they were only 8 credits shy of graduation instead of a full 16.</p>
