Where I went (MIT Media Lab) our classes were unique and only graduate level. In fact masters and PhD took the same classes, PhD just took more of them. There were no undergrads, and the knowledge assumptions, type of classes, and speed were very much more advanced than undergraduate. During my undergraduate (UCSD) I took a few masters classes — they were definitely harder and assumed a lot more knowledge with less hand holding. YMMV.
