I hated homework, and I think that teachers can often put far too much emphasis on it's importance. I got away with doing barely any homework or just making a poor attempt with little effort. I still passed all my clases with decent grades, homework doesn't have that much of a difference. I spend all day at school studying, then the couple of hours I get of "free time", I have to spend half of it doing even more work? Screw that.
I don't think homework should be gotten rid of entirely, because when you get older and go to college, university, and also many jobs, you will need to do some work at home. Homework at school will help you get into the habit of independently studying and being able to manage your workload. So they should definitely keep it. Some schools need to cut down on it though, by a lot. It's something that becomes increasingly more important as you get older, but before then it should be a lot more relaxed. I swear I got far more homework when I was 10 years old than what I do now at college.
