Question

your friend often insists that you do your homework together but they copy

Answer 1

I think you should tell them to not copy as it will not help them in the exams.Because they won't learn the fact if the don't solve the questions by themselves.If they still don't listen.I think it is better to do homework alone.

Answer 2

Self help is the best help. Let them do their homework on their own. You don't show your homework to them and let them copy by making them lazy. Then they won't learn anything but just inherit the habit of copying and even in exams. So friend don't ever do this mistake! Instead help them who don't understand some problems and have doubts not the lazy one who does nothing rather than copying yours.
