Why you should not pay for this course on edx.org

This was my 6th course in MITx series. I remember that day. A slight twilight behind the window indicated the end of a decently hard working day.  We had just finished a massive (60 pages) review paper on some polymeric stuff with my colleagues, when I came across this wonderful, as I thought, opportunity. MIT had launched a MicroMaster's program in Principles of Manufacturing and the first course was dedicated to the statistical process control. "Here we are",- came into my mind. God, if I only knew.
