A useless test taken by all Irish teenagers halfway through secondary school. It involves learning a tonne of shit that you'll forget when you're 18 like everything else at school, only in this case the result has no effect whatsoever on your later life.
Kid: Why do we have to study so hard?
Teacher:It's all going to show up in the Junior Cert.
Unfortunately the conversation ends here as nobody has enough balls to say,'why the hell do we do the Junior Cert?'
