<em>I still assume that grades measures exactly what a student learns. It usually shows you whether you've got wrong or right when you finish an exam, and it explains why and how. If a teacher or student scores your paperwork and mistakenly labels you wrongly, grades will also be incorrect, even though you deserve a much better score. Plus grades are not that significant, actually. Students should concentrate on studying new subjects and real knowledge, since that is what a student really represents.</em>
