Today, the purpose of education has changed in Korea. There are some who think that children should be competitive, there are others who believe that children are taught to cooperate and become more productive adults. There are advantages and disadvantages to both arguments. For starters, what is good if a sense of competition for children is implemented? They can develop themselves more and more as they learn and research a lot to win the competition. To prove this, in Korea, it is very common - even popular nowadays - to have a tutor come to a student's house to teach additional learning sessions with paying a lot of money. They learn faster than what they learn at school. Moreover, during vacations, students study abroad to learn English for a month instead of revising at school. If they have experiments like studying abroad, it is one of the biggest pluses to the famous high school. Moreover, there are four major examinations at school and two national examinations to test students' academic performance. In general, only the highest 40% can enter good high schools and colleges. On the other hand, when they are busy going to school and studying separately with private tutors, there is a problem. They become selfish. They become careless and do not help others a lot if it is about research.
