Firstly, I'd like to tell you about advantages. Doing homework after school is completely useful activity, because it promotes to fastening material of today's lessons. If you didn't do your homework your teachers and parents would be angry about it, so, I think that every student should doing homework everyday.
Then, now I want to tell about disadvantages. Sometimes, teachers asked too many and hard homework for one day, so, students can't do all their homework in time and became very tired.
