England has got a very interesting system of education. Education is class-divided in England . There are some state schools in England . They are infant schools, junior schools and secondary schools.
British boys and girls begin to go to school at the age of 5. They draw pictures, sing songs, play games, and listen to the stories and tales.
British children begin to read and write when they enter the infant schools.
Little children are divided into two groups, according to their mental abilities. Children leave infant schools when they are 7 years old. They begin to study at junior schools where they learn to write, to read and to do mathematics.
Boys and girls have got many interesting school subjects. They are History, English, Geography, Mathematics, Art, Music, Sport, Computing, and Cooking.
