Yeah I think so. I was shocked to discover that over a 1/3rd of the computer science classes I TA'd as a grad student were cheating, repeatedly, on homework assignments and tests. I had come from a culture as an undergrad (and graduate student at another university) where cheating even once was a potential expellable offense. At the very least you would fail the class. In the comp sci classes I TA'd the professor would fail the students for the assignments but no more, even after multiple offenses.
