Cheeky pupils put their school up for sale without teachers knowing so they would not have to sit their exams.
The sixth form students erected an estate agent 'For Sale' sign outside the impressive property earlier in the week.
But agents Buckey and Ward alerted Borden Grammar School in Sittingbourne, Kent, after they received several calls from interested people.
A pupil said: 'It was just a joke. But I think some of us were hoping it might get rid of the school so we would not have to sit our exams.'
