A 'contractvak' is an optional extra course designed for self-motivated, academically capable students who wants an extra challenge. It counts as a full-fledged exam subject but scheduled flexibly in the timetable, where the student is responsible for managing class appointments, contacting teachers, and meeting test and assignment obligations.
