The ugly truth has been spoken

I think that quote is dead on.

*Waits for shitstorm*

True a school is meant to motivate us to learn and find out what we are good at, not give us numbers that tell us how intelligent we are in a subject that we just so recently learned

Students cheat because it's easier than actually putting forth effort, guarantees a certain level of success, and because they can. Students cheat for the same reason people cheat outside of and beyond school. There is no big philosophical or social message behind it.
