First, time is too short for students to enjoy their lives. Students are not studying machines and should not be people who know only studying. They should have more activities with friends such as exercising and discussions. Communications through those activities can energize their lives and will teach students social skills.
This policy gives rise to the possibility of a half-learned education. There are students that don't try to understand, just memorize. But math and science are subjects that require understanding rather than memorization. If committing things to memory is the only thing a student knows, he or she won't last long as a scientist.
Aptitude is more important than knowledge. There should be more activities for students to figure out their interests in life. For example, experiments and research makes students curious and allows them to develop interests in math and science. Such activities are helpful to students who think the most important goal of education is getting a good grade.
If this policy continues, it will not only damage the futures of students also our country's future, so the government should end the early graduation policy and add more research and cultural activities to curricula.
