korea education problem

(i need grammar check and the limitation of my solution
also, if there are awkward expression,point out please...i need your help)

Korean students are forced to choose a permanent major too early. Korean high school education offers two different curriculum options: liberal arts and natural sciences. While liberal arts students learn about society, the economy, history, etc, natural science students learn mostly about math and sciences. This curriculum takes away the chance for students to study other fields. As a result, this makes students unknowledgeable in other fields. When the students become 17, they must choose what they will study, but they are too young to make any informed decision. They don’t have enough educational experience to choose wisely. Some students regret choosing their majors when they become university students, and, in the future, they may even cry over their job. In most cases, many students lose interest in their studying and become uncertain about their future.
Therefore, we should let students study any subject regardless of their highschool choices until they go to university which will give them more time to decide. After they choose a curriculum, liberal arts students should learn about natural science and natural science students should learn about liberal arts. When they become freshman in university they should take any class they want and decide their major in their second year. Students can then experience many fields of study and make up their mind on their majors. As a result, more students will be satisfied with their majors. But, this won't work for specialized education, and it will be confusing to many. Because of this, it will be hard to implement.
