Why is it important to do assignments?

Home work is important so is school, if you want a good job when you get older do your homework, if you don't you might get into trouble, if you don't that's your problem you wont get good grades, i get heaps and my brother doesn't get any i don't think its fair because we go to school so whats the point of getting homework too. I think ti matters.

i think pupils should have a choice and there should be a suave sent out to all parents about homework
