I have a take home exam for one of my classes and the material is really hard. Would it be considered cheating if me and my friend answer it together? It is an online exam and the professor is giving us only 1 hour to answer it so she told us that she assumes that we are not going to use the book. But i don't know if she means that we are not allowed to use the book
I think you know yourself that this is cheating. It is not what is being asked of you by your teacher.
Better to do it properly and fail, than to succeed and know that you do not deserve the better mark you may win.
If they think it is not allowed then it is not allowed.
