I went to one of the better University of California campuses like 20 years ago. And my friend majoring in CS told me a CS professor caught about a third of his class cheating in their take-home programming assignments. This was in a lower level CS class. He ran an analysis through turned in assignments and discovered almost a third had patterns that signaled it had been copied from someone else's work. This is before github so the suspicion was that some were copying code from other classmates. We will always have cheaters.
