Geez, I got robbed when I was at school then! I can recall having formal classes right up until the last few days. Somewhere in the last week would be the "Awards Ceremony" (which the Yr 12's came back to - go figure!) and reports were handed out on the second to last day. The last day was "clean up" and hardly anyone went. My Mum made me go one year and a whole 4 students showed up (out of the entire school!). Every year after that I let Mum think I was going to school but went to a friend's instead.
Of course, the "Cool" teachers let us do "fun things" in the last few weeks...
