Is your son, or daughter, a nerd?

Is he, or she, an indifferent student? Take heart; according to a piece in the Times today, your teenager could grow up to be a billionaire (my emphasis): 

As a child, Michael Bloomberg was a nerdy but middling student, president of the Medford High School slide rule club and briefly in charge of collecting dues from fellow students. 

Bloomberg was also captain of the debate team and a member of the Science and Technical clubs (surprised?).
