We've only got this term here - and then we go up into the sixth form! Fancy being at the top of the school!
The O'Sullivan twins and all of their friends are almost the oldest in the school now - but that doesn't stop them wanting to play jokes and cause mayhem! The teachers think that they should be a bit more responsible - and can't decide who should be head girl. Will the most sensible girl be chosen, or the one with the best sense of humour . . .?
