a　sense of guilty

Tomorrow, i will have a ＂negotiation" with a stranger who afford help for my friend's exmaination. for me, this is the first time to go about this kind of business, with a restless and unesay heart, but i must to try it this time for the sake of my friend. This motivation reminds me of thinking the exam system in our China, which is contray to American where the similar thing like plagiarism is forbidden. however, even in our University, the numerous device of cheat pasted everwhere in the corner, and it seems very natural for each student.what's more, the cheating tool is so advanced that beyond a common people's imagination. someone said that it is the inevitable product of examination, but how it happens ? The factious activtity exists in many fields besides in study, and the so-called measures is not but only hollow slogan from the senior.
