<p>I am not a stundent but what we were told is you can cross register at Carnegie Mellon if a class is not offered at Pitt and if there is room in the class at CMU.</p>
<p>That’s what we were told by the head of the CS dept when we visited last year.</p>
<p>It’s also not just limited to Pitt and CMU,</p>
