<p>This is only true for certain disciplines, as I said above. CS was certainly one of them. EE might be another. However, I certainly know that the math department explicitly discourages its students from returning. My friend was accepted back into the Ph.D. program, but when he talked to someone about being nominated for a fellowship, the professor actually told him flat out that undergrads are discouraged from coming back in general, THOUGH in his special case, he was a transfer student, and so it was kind of a different deal.</p>
