Junior Cert

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?'

leaving cert

The last exam you'd take in an Irish secondary school that if u try to study for you'll turn from looking 17 to 42 years old, completely f*cks up your sleeping cycle and you'd be lucky to survive.
