edX, a nonprofit organization offering more
than 200 free on-line lessons from greater than 45 companion universities in six core areas:
business administration, laptop science, engineering, humanities, social sciences, and
statistics and information evaluation. In March

professionals from 2,000 organizations that grossed almost $1.Seventy five
million.
