Until now, many countries have mandatory course for their students until they enter the college. It is beneficial to students to have same amout knowledge in their schools. Also, I agree this recommendation because these reasons.
Even if students have extraordinary abilities to study, it just will be some specific parts of academic fields. Generally, most ordiany students have abilities to follow their study through their courses. For all students, if people want to be had same knowlege and same academic background, the national curriculum is essential. Of course, some people don't want to follow their mandatoyr courses so that someone takes privite classes in their house or takes a different class in other substituted schools. However, if students want to enter the college, they have to take a national test, for example, SAT. Like this test will require generalized knowledge until in the high school. For preparing this test, every students have to study requisited courses of SAT. Even though some students take privite courses, they also have to prepare these classes. Because of this, national curriculum is needed. If they do not need to take a test to enter the college, they won't prepare these classes. However, until now, every college wants to accept to be experimented students so that they need standarized test for everybody. Recently, even though national curriculum is becoming a social issue to criticize its efficency, if governments don't change their policy about thier educational programs, it has to exist in the education.
However, the same national curriculum has some troubles. If one student doesn't follow the same curriculum, this student will be fale to enter the college. The mandatory curriculum does not allow individual characteristics, some students who have surprisingly abilities for other fields, for example, playing chess, singing the classic song, and operating computer systems, will not enter the college. So, we should consider this problem in the same national curriculum.
Nevertheless, the system of the education will not change to allow other possibilities, a nation has to require all of their students to study the same courses, until the college. It is related to educational systems so that it is difficult to decide whatever is right. However, while the current educaitonal system exist a nation, the country should require the same curriculum to its students.
