Canadian experience for an IB diploma: 6 year-long courses generated the equivalent of about 1.5-2 hours of homework per night, on average, in grades 11 and 12. Because of laptops in class, almost all homework was completed in class time in parallel to lectures and required little to no out-of-school work on weeknights, with maybe 4 hours total on weekends dedicated to longer-term projects.

This left ample time for socializing and extra-curriculars.

What is to give light must endure burning.
