I had a professor "borrow" test questions when I was in graduate school. It was a take-home test and I did a google search for a portion of one of his questions and found it on a class website at a totally different university. Also, one of the true-false questions disagreed with our textbook but I still got it wrong because I didn't answer the same as the stolen test. I pointed it out to the professor but he refused to give me more credit because it was only one point and not worth his time. Unfortunately, I missed class the day he was reviewed.
