Imagine there are two students, one is good at getting high score in the exams and the other is good at many practical skills, so who will be popular? In school, there is no doubt that teachers like the former person, because education pays attention to the exam, and score is always the standard to judge a student. While in the job market, the latter is favored by the employers. They expect someone who has the practical skills and can make profits for the company. Score doesn't mean ability. In school, some talented kids will be ignored because of low score. They are easy to miss the chance of making differences. So we can't judge a person by score, which ability is also the important part to measure a person, even ability take over the score.
