I have a student who is extremely low in one of my classes. I am 99% sure that he copied off his neighbor for his test because he made the same exact as him and he solved some problems "correctly" when I know he is not capable of it. He even has long division work done out on his test without any #'s in his quotient. I tell this kid to come to extra help every single day and he never shows up...and the poor kid cannot do anything. I have two options-- grade him very harshly. He would get a 40% in this case. He copied one # incorrectly off of his neighbor so I could take off full credit for that. (His work doesn't make sense with the one # copied off incorrectly.) I could also talk to him about it and offer him a retake. I should have done privacy folders for them but I moved the desks from groups and I didn't feel like passing one out to each pair.
