I took this Mathematics class and this student asked me if I could ask the teacher to send my test so I could send to him so he can study for the test. It's not that I don't want to be a good person but thinking about doing it is eating me and I feel if I do it so many things can go wrong for and ruin my future. What should I do?
You’re under no obligation to provide your friend with a copy of the test, particularly if it makes you feel uncomfortable. Just politely decline, and if pressed further, say that you don’t think it’s appropriate to ask the instructor to share the materials that way.
As for the possibility of a penalty, I would not share “active” materials like quizzes or exams that other classmates still have to take, because that could be viewed as an academic code violation. Sharing something that everyone has completed and received grades on may or may not be penalized, based on an instructor’s or program’s explicit rules.
