Do students have a means to submit their paper to Turnitin prior to submitting it to the instructor? A have a paper showing a 100% similarity score relating to a paper submitted already to my school. I asked the student to explain this and he said that he had submitted the paper himself to Turnitin prior to turning it into me. I was informed that if this was the case, I should show 2 submissions for this student, which I do not. Does anyone know how this process works?
