to much homework make us stupid

I definitely don't agree. I don't think that homework makes you study. I think that it's to help you understand what you're learning. You might feel that it's useless, but I really don't think that it is.

I would disagree with you. In my experience, homework helped me a lot in understand a topic better or to find ways to apply it in a realistic stage. For me, it's a useful tool, though I will admit that there are times when I get frustrated and infuriated because of the homework's difficulty. But I get rewarded by learning to the right thing or method to accomplish something that I can use in my future career. That's what matters to me in the long run.

You may feel homework is useless but it helps move the class along the lesson plan aswell as build character. Besides you need to start somewhere before you can learn the real interesting stuff.
