In Enid Blyton's bestselling school series Elizabeth Allen is sent away to boarding school and makes up her mind to be the naughtiest pupil there's ever been.

In book eight, Elizabeth is desperate to play the piano in the end of school concert. Elizabeth knows Arabella is very good - so she spends every waking minute practising. But exams are looming, and piano practice leaves Elizabeth with no time to revise.

Will the Naughtiest Girl have to stay in First Form another year?
