At least in my cohort and my university, cheating was endemic and done by almost everyone on every assignment. Not cheating was a significant disadvantage. I didn't ever hear of anyone getting caught which I find astonishing, since I'm sure the graders were faced with multiple identical answers.

Maybe because the subjects were quantitative, there was less scope for plagiarism detection? Or maybe they just didn't really care, or they didn't want the administrative trouble. I'm not sure.
