Lacking such a technology, people find it difficult to achieve their goals. Knowing how to study is vitally important to anyone. The first little gate that has to be opened to embark upon study is the willingness to know. Such a system only produces graduates who can possibly parrot back facts, but without any real understanding or ability to do anything with what they have been taught. Until you clarify that, you cannot make an intelligent activity of it.
Some students study for the examination.
That is complete folly, but unfortunately is what many students have done in a university. Take the man who has been building houses for a long time, who one day gets an assistant who has just been trained in the university to build houses. The academically trained man has been studying it for years, yet knows nothing about it. And the practical man doesn't know why this is. That is the basic and important difference between practical study and academic study.
