I expected to find around 50 or so free courses out of an active catalog of 2, Coursera courses. Imagine my surprise when I found more than 1, Coursera courses 1, to be exact that are still completely free including the graded assignments, minus the certificate. All of the Coursera courses on the following list are completely free. Below is my list of all the 1, completely free online courses on Coursera that I was able to find, along with their ratings by Class Central users.
