This is perhaps not such a problem at private training institutions, but at most uni's cheating in assignments is becoming a real issue (and I have personally busted quite a few people this year).
I guess this post is really a warning for students: do something stupid like this
and you are going to get caught, and it is likely to get you thrown out of uni if you do it more than once.
Also most uni's are using tools with huge databases of textbooks, thesis and journal papers that scan through written work submitted by students, and bring back the full texts of similar work. Automated plagiarism detectors.
