Well, I hadn't not heard about that. The ones I've taken are good quality in my opinion (writing essays, qualitative and quantitative research, understanding research, and seeking information). I hope that statement is true only for some courses.Does anyone think Coursera has really gone down hill? When I started doing them last year I thought they were brilliant, it was the best thing I had experienced in years - free education. But now, the quality of the courses seemed to have declined, and they're more orientated towards business and not much else (I'm keen on sciences, in particular biology). However Edx has improved and offer some excellent and high quality courses, at a higher level too not just introductory.
