The Sir Henry Floyd Grammar School improved its A-level results on last year with 90% of grades achieved being A* to C.
It marked a 3% improvement on results last year for the school and headteacher Stephen Box said: “We are genuinely thrilled this year to see a set of results which are such a fair reflection of all the hard work that students and staff have put in.”
All of the school’s applicants for Oxford and Cambridge were successful.
Mr Box highlighted one student, Dominic Applewhite, for special mention. He got 2 A*s and an A, while also acting in films such as The King’s Speech and Les Miserables.
