 For much of the 20th century , it was a non @-@ fee paying voluntary @-@ aided school , but following local council plans to remove this status and merge the Grammar School with a nearby secondary modern school , the governors took the decision to become fully independent in 1983 . Now a fee @-@ paying day school , 650 pupils aged 4 to 18 attend from the three counties of Cambridgeshire , Norfolk and Lincolnshire . Following the closure of the nearby St Audrey 's Convent , a significant feeder for the senior school , a new junior and infant preparatory school was opened in 1997 , now known as Magdalene House .
