School really gives us a lot. This is a real school of life. We definitely get knowledge on school subjects. Besides, teachers teach us ethic, morality, discipline, speak properly and express our thoughts. Teachers help to form the basic life goals. Both public and private education have their own advantages and disadvantages. In a private school teachers more attentive to children. But not everyone can afford to pay for education. In a state school children are less arrogant and more friendly. But in a state school then give general knowledge without advanced study of definite subjects. I don't which school to study in b cause a lot depends on pupil's own efforts.
