Higher education
Through a higher education, people can improve their practical knowledge. That is, students who take higher education can adapt their knowledge to works in the future. For example, student in business course learn how to estimate profits, make products efficiently and induce customers to buy the products. When they work in the future, they would be better than other colleagues who didn't take higher education. Also, most of the students in higher education receive a chance of practice, especially in medical course, and they will work in the future based on practical experiences.
To sum up, i believe that higher education makes students be skilled at practical work by adapting their knowledge experienced in higher education.
