Scotland
In the Scottish education system, the final year of school is known as Sixth Year or S6. During this year, students typically study Advanced Higher and/or Higher courses in a wide range of subjects, taking QS exams at the end of both S5 and S6. Pupils in Scotland may leave once they have reached the age of 16; those who reach 16 before 30 September may leave after national examinations in May, whilst those who are 16 by the end of February may leave the previous Christmas.
