What age do Sweden people start and finish school?

In Sweden, children typically start school at the age of 6, enrolling in a program called "förskoleklass" (preschool class) which is part of the compulsory education system. Compulsory schooling lasts for nine years, concluding around the age of 15. After this, many students choose to continue their education in upper secondary school, which lasts an additional three years, usually finishing by age 18.
