The fact that we are so fixed on HOMEWORK instead of testaments that more relies on how one's knowledge holds is in itself a problem, probably bigger than the one presented in the title.
I mean, if you really don't want to do the homework and you're confident in everything your teacher is teaching you, then tell your teacher or have a brief chat with your professor to see if it's possible for you to ask for some of the assignments to be reduced.
On the other hand, copying homework is considered cheating or academic misconduct, and I don't recommend that anyone do it. It makes no sense to cheat both yourself and your teacher by doing so.
Well, then the teacher might say, you need to practice to be better at it. But for me, if my assaignment is simply solving equations, then there is no point practicing it. I would actually copy homework just to save the trouble asking and think about what to do if the teacher says no.
