Student cheating is a systemic part of the culture and there is nothing that can be done about it.
I mark logic papers. There might be a question where you have to provide a model that makes the logical formula come out as true or false - the sort of question which has an infinity of possible answers.
They never follow the particular method I suggest for working through these which would lead them to the simplest answer in each case (usually a model with only one object in the domain). Yet, somehow, one paper after another, they all come up with the exact same model, with the same number of objects in the domain, the same extensions... everything.
So they all just copy from one another. One student complained to me this year that a large group of them were copying answers from one another right in front of the office where they have to submit papers. Largely the university can't do much more than turn a blind eye - for without absolutely concrete evidence the students can (and often do) sue, and win.
