Six months ago self-confessed "teenage tearaway" Terri Moss was not expected to pass any GCSEs - and she could not care less.
Wild child Terri missed more classes than she attended.
But she finally decided to change her ways - and was rewarded yesterday with eight impressive GCSE passes.
Students across Sussex excelled themselves when results were published, with the overall A* to C pass rate rising to a record high of 57.9 per cent.

Terri, of Brede Close, Whitehawk, Brighton, said: "I always used to be skipping lessons and I gave my teachers a lot of abuse.
"I'm not sure why but about half-a-year ago I decided to knuckle down a bit more."
"I'm happy enough with my results but I could have done better if I'd started working earlier."
