university, grumbles about a problem that he has been encountered with most of his
students in the past ten years. He figured that his students are worried about their grades,
however they don’t put enough efforts based on the grades they desire. On the other
hand most of his students are studying engineering and science. They answer the exam
questions partial, but they are not able to have the final answer correct, therefore it is
impossible for those students who have a responsibility to build a bridge or do their jobs
precisely. Not only the students’ view point is devastating for themselves, but also it is
pernicious for the society.
