Cheating in school work

since i goto a public school , and what they teach is mostly lies and other stuff, is it permisible for me to copy the work from a friend ..

i dont want to goto a public school because of the harram eviroment, but my parents want me to go, so i obey them.

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

It is not permissible for you to copy school work from your classmates, because that is a form of cheating and we are forbidden to cheat. The Prophet (peace and blessings of Allah be upon him) said: “Whoever deceives us is not one of us.” And that may also result in a great deal of harm in this world and in the Hereafter. So you must beware of that and advise others to avoid it.

But if you see the way someone else does the homework and you understand it, then you close his book and write your own answers, there is nothing wrong with that. And Allah knows best.
