Why do we censor in Schools?

QFT
grades arent always showing how smart you are, they show how bored you are. i know a few very smart people which fail many tests due to laziness.

I know a few people like that, they don't do the work, they won't get the grades, and boy are they going to be pissed when they don't get into the universities they want at the end of this year.

Not doing work you get that contributes to your actually grade means you are stupid in at least one way.
