  Thomas Alva Edison, sold newspapers, nearly set fire to a train, ran away from the court when it was in session and much more..... he was the one who gave the bulb and gramophone, gave technology new life. Still you judge little kids by their grades their marks and strange things like IQ, more absurd things are on their way. present education system only teaches and tests memory rather than analysis, innovation and creativity. genius are rarely good at mathematics, so was Albert Einstein. each child is a genius in his own god given skill, learn to teach and train them.
