The OP has gone, probably the deadline has passed. In my campus, there's a demo session with student's assistant in order to prove that you are the one who really writes the homework/assignment, at the very least you must understand what you submit. Failing to do so ends in 0 for the respective homework/assignment and a "yellow card". Another copy-paste effort and you have final score of E ("red card"), which is the lowest one and in case of compulsory subject, you have to take it again next semester or next year, depending on whether the subject opens up or not next semester.
I stop acting as a teacher/assistant, as most of these students don't really want to learn and understand. They just want to get their homework done and goodbye, without thinking what will happen to their future if they keep doing this way. So when the trade idea comes from skalogryz, I agreed right away. It could control my blood pressure and at the same time adds donation to Lazarus (if I get one).
