I think exceptionally good students(exceptional students) should be allowed to skip grades. I have some reasons why I think so. First of all, being able to do something you want to do and do at own your level may be very good for you. Therefore, I think studying in the upper grades stimulate students' motivation for academic endeavor. Another reason is that grade-skipping doesn't need extra fees for tutors or separate programs. The desire of the student to study reduces the cost needed. It will be very helpful to poorer families if the costs of learning were reduced. I want to eliminate the situation where students can't go to college simply because of their financial position(I would like to see the day where no student is denied a college education simply because they cannot afford it). In other words, I want a society where people who really want to go to college can go(can do so). However, grade-skipping has a disadvantage that causes mental stress to grade-skippers. In addition they may feel that they were underachievers. Although there are some disadvantages, there have been many grade-skippers who contribute to society such as Son Masayoshi and John Bardeen. For these reasons, I think exceptionally good students(exceptional students) should be allowed to skip grades.
