<human>: This is the story. My friend K knows W. W and K both have similar last names so were placed in the same SAT classroom. K and W both received their respective scantrons when entering the room, but then surreptitiously switched. K now had W's scantron and will get W a good score. W had K's scantron, but K just canceled his score report immediately after. W will end up getting a really high score now. The part that I'm worried about isn't the fact that they cheated, its the fact that K could get in trouble. He doesn't believe me though. I told him to just cancel both scores because I just have a bad feeling about him getting fucked over by this. What are some things I can tell him where he can get caught by doing this ? Thanks
