I'm old so when I was in school the internet was barely a thing and certainly no google, ratemyprofessors, youtube, and things. So cheating for me was like not reading the book but going to the library and getting the Cliff Notes or Spark Notes instead, or renting the movie. It was always different, but usually good enough to get you a B or C.
Some of the creative things by the time I was in undergrab was like taking answer and writing them on the inside of the label on a bottled water, saw people putting answers under the brim of their hat, put the answers on a piece of paper face up and in the desk of someone in front of you, just that stuff pretty much.
