cheating on tests should not be compared with real cheating ex. cheating someone and leave him/her without money and causing them real troubles
I think cheating on test can be like food, it is haram to steal, but in certain conditions it's not haram to do that.People sometimes are just stressed out,and they don't do it to harm anybody, they just do to get out of the situation they are, and usually in elementary school, highschool this is done, bc you are still sometime afraid to tell your parents that you got a C in some subject.
