Recent memory research supports the way they structure the testing. The repetition and redoing things until you get the score of 100% not only shows sticktoitiveness, but the process improves retention. Also, the way they have the video lectures stop and ask questions which require the correct answer before continuing improves retention. So far, all the courses I've looked at have a free option, but some are more free than others. One course I enrolled for would let me take the tests, but wouldn't grade them. Guess what I didn't finish? What do the certificates look like? Do they name the school providing the class? Lots of colleges and universities are offering courses on coursera. Some charge more than others for the certificate. In theory, the value of the certificates should be affected by the outfit presenting the course. What does it matter who gives the course if the certificate is going to only say coursera? A certificate from a famous school is a certificate from a famous school. Coursera is just a classroom.
