I grew up in Greece, where we go to a second school (private classes), after the main (public) school. And they both assign you homework. We are talking, 7 hours of public school + 3 hours of 'private' school (we call it 'the after school'). So 10 hours of being physically present at some kind of school and then homework from both of them. So expect 2-4 hours of homework added on top of that. 10-14 hours school days. Yay!

You might be wondering why the "after school" exists. See, you need to attend the public school (or an accredited really expensive private one) in order to advance through the education system. But because public school suck you go to the second school in order to really learn. As to how much the public schools were I grew up suck, we are talking kids having sex and filming it during school time - and the teachers dealt with this by banning cellphones to the school. No cameras, no recordings!! When I think back, I honestly feel rage with how much wrong the system was.

Anyway, of course this meant you had to be physically present at some kind of school location for 10 hours per day, and then spend 2-4 hours doing homework in order to keep up. I remember people defending that system to death, making fun of america's homeschooled children and finland's relaxed attitude and how we are the "real heroes" of the education system. Ugh.

PS. I just remembered. We even had homework to "religion class". Oh yeah, we learned about the life of jesus mostly, in theory we had to learn about other religions too, but it was mostly all about the J. So, of course we were given homework even to that too. Ugh ugh ugh. Not a religious school btw, a regular public one. Complete with "why didn't you learn the creed of faith, are you not a chistian?" attitude from the teacher towards 8 year olds that didn't study. What a shithole.
