Prince George, Princess Charlotte and Prince Louis are all students at Lambrook School in Windsor which is located just a stone's throw away from the family's home at Adelaide Cottage. Lambrook - which caters to students from the age of three to 13 - charges an increasing annual fee as the children go through the school, meaning that the three Wales children's education will cost an approximate £62,979 a year.The school's ethos is all about being kind to one another, as well as having courage and integrity - something which will certainly serve the three royals well as they grow older.
