The rule of thumb in university is 1 hr of home study for every hour of class. So 2 hrs of homework for a 12th grader in seven classes doesn't seem unreasonable. The following year as a college freshman, they are going to have ~3 hrs a day of homework.

The rule for college/uni I've always heard (and repeated to my students) is 2 hrs outside of class for every hour in class. So a 4 unit (= 4 in-class hours/week) class should have 8 hrs of outside time dedicated to studying and homework.

if this was the case for everyone I never would have had a chance at graduating while working multiple jobs
