Homework is very important and necessary! Homework helps us to know and practice our errors. Without homework, you wouldn't know if you pretty understand the lesson or if you really know what the teacher is talking about. It is necessary for teachers to give students homework to help them from avoiding to struggle in exams, quiz, and test. Homework is our main proof to prove to ourselves that we really learn something. We always hate what is good for us, we keep on complaining towards the things that is hard for us to do, and we keep on denying to ourselves that the things like homework really help us in times of needs like exams. It helps us remember things and give us knowledge to stock in our minds for future use. Just remember that, "There's no gain without hard work" and that "practice makes us perfect".
