In my engineering school in Poland everyone was given a different assignment, so copying off other students was not possible. Other pathology occured though - since most of the tasks were group assignments (with the usual group being 2-3 people), it was common for a group to just divide the workload among its members across multiple courses, which in practice resulted in a possibility of getting a grade for course x on which one didn't do any work (because he was busy doing group's assignment for course y). The cool unintended consequence of this was that the whole studies were a multiyear training ground in team organisation and negotiations, which is arguably worth more in real life than some of the highly theoretical courses.
