thaitam 9 / 14 Sep 5, 2010 #1hey guys! i need all your help to be better in writing. thanks in advance.!by the way, can you let me know that my essay is short?Grade is a mark given in an exam for a piece of school work. Students need grades as an assessment for their capacity at school. Good grades are the target, which students have to achieve if they want to step up the higher classes. Therefore, I totally agree that grades encourage students to learn more.Grades motivate competitive spirit among students. Indeed, students defeat with each other by studying hard to get high scores. For instance, when a student gets lower scores than his classmates, he might ask himself: " Why do not I have a high grade? How can he get this grade? is he better than me? I think we ourselves at least one time ask these questions.Good grades provide students knowledge. Grades evaluate one's capacity and perform one's attitude towards studying. Obviously, if a student has low grades, it means he might not understand the lessons. Therefore, he needs to chance the way he studies so that he enable to understand lessons and master concrete knowledge next time.In sum, grades are the essential part of one's studying. Without grading students do not bother to study hard, cope with challenges, overcome difficulties, or perform self-discipline. Therefore, grades motivate students to work harder.
