A famous theatre school.

Do you love singing, acting or dancing? At a theatre school, young people learn how to become actors, dancers and singers. There are many theatre schools in the UK. One of the most famous is the Sylvia Young Theatre School in London. Children aged between 10 and 16 go there. There are about 250 students at the school. Famous students from the past include the singers Leona Lewis and Dua Lipa.

At the Sylvia Young Theatre School students study the same subjects as students at other secondary schools, like maths, history and science. Students also take the normal school exams at 16. They do these school lessons on Mondays, Tuesdays and Wednesdays. Then they do dancing, singing or acting classes on Thursdays and Fridays. There aren't any lessons on Saturdays or Sundays. You can also study at the Sylvia Young Theatre School in the holidays, and they do classes for adults, too.
