A near-impossible problem put on engineering or science exams to determine who is using online resources like Chegg. Works best for take
home-exams, since a student would be able to Google the problem more easily in a non-proctored environment. A professor will typically enlist a teaching assistant to post a convincing yet erroneous answer on sites like Chegg ahead of
time. Also known as a "cheat
check".
Joe: "How'd you do question
5 on the thermodynamics exam?"
John: "I found the answer on Chegg. It looked
right."
Joe: "You fell for the Chegg
bait. The TA posted that answer, and there's an intentional error in it!"
