After completing S5, students can usually go to Scottish universities. English universities may require students to study to Advanced Higher level (S6), given that the Higher is equivalent to AS-level on the UCAS tariff. As Scottish university courses traditionally have a duration of 4 years, the loss of one year's schooling is compensated by an additional university year.
