Notes:
- Courses in the same timetable category (A – F) will be taught at the same time and therefore cannot be taken together as part of a Diploma programme.
- Online courses are listed and although they are not timetabled, they are part of the curriculum. Students work during tuition hours on the on-line course individually. Each week online students will study during tuition hours for not less than four and a half hours and this equates to the number of hours of lessons for other DP subject courses.
