The number of subjects taken during the academic year depends on whether the school follows a semester or a linear (full-year) timetable: in the first case students choose 4 subjects per semester, in the second they choose 8 subjects carried through the whole year.
The Canadian high school curriculum is broad and designed to give a rounded education. Students take compulsory courses in core subjects such as:
Mathematics
Sciences (biology, chemistry, physics)
English or French language and literature, depending on the linguistic region
History and geography
Physical education
Alongside these there are optional courses that let students shape their studies around their interests and future goals, such as art, music, computer science, economics and foreign languages.
