At the start of secondary school, students can enroll in Specialist Classes if their grades from the previous year are good enough. These students specialize in a particular subject; this can be any of the subjects listed above, except Technology, Physical Education and Civics. Students enrolled in these programs have a heavier workload than regular secondary school students. The workload varies from school to school, but grade 11 students are generally expected to study grade 12 courses concurrently. Other courses include university-level courses. Some schools go as far as requiring their students to finish secondary school by the end of grade 10.
