So Much Unfairness ending

I think that since P.S. is such a sincere and good-hearted person that he will end up turning himself in and telling Dr. Fairbanks that he cheated. While P.S. is cheating, we are told that his heart is beating wildly in his chest, and his hands are shaking. I think that this tells us that he is nervous and does not like what he is doing. Even though P.S. wants to please his dad and pass the exam, i still think that he is too good of a person to let himself cheat and not do anything about it. He knows that it is wrong and this is why I think that he will turn himself in.
