If sitting in the back and cheating guarantees a good grade, that's a shit school, honestly. The school seems to know that people cheat, and how, but nothing is being done. Randomize seating, have a proctor stand in the back of the class, suspend/expel people who are caught cheating.

Ya it drives me crazy. I know someone who scored an 81% on a midterm where a few people scored in the high 90%. The professor told them, that among the people they didn’t suspect of cheating, they got the highest score. No curve, no prosecution of the cheaters.
