The master of class clowns, and those who need to wake up to themselves. Why their parents can't do a good job is beyond me, but at least this teacher stops them in their tracks.

Mr Costello was really kind to me, i dont really like him that much because everyone else in the class has issues with him, but i did get a good result in the final test and he was happy with me

He's so boring, I fell asleep the whole yr 11. Talks in the lowest possible volume. And I'm a disciplined student...
