Coursera will not grade the end-of-section quiz for non-paying students.

EdX grades exercises for audit students, on every course I’ve done there the free/paid experience is identical, the only difference is whether they issue a “verified certificate” at the end. Often people audit courses and only upgrade to paid once they have a passing grade.

I just found the first couple of courses on edX where graded exercises are only for those who pay for a "certificate". It's all courses in a UC San Diego "MicroMasters" program around data structures and algorithms. That's all the programming exercises, more than 80% of the value of those courses for most people. Unfortunately I found the quality not worth the price, and I would say that is true even for beginners (I have a CS degree from 20 years ago and only watched to remember a few things I forgot, just for fun).

Anyway, I think this might be a sign for the things to come. A lot(!) of edX courses, despite being okay or even good, have very low participation judging by forum activity. I think the course makers at the universities are going to feel more and more pressure from money-counting management about cost/benefit for the institution.

It's sad that to me to see that everyone does their own (often inadequate) little course instead of working together to create something bigger, better. I would like to see platforms like edX and Coursera not as market places like Ebay for lots of still very traditional little courses, but as platforms that encourage jointly working on something better (in addition to the current model, not as total replacement). Of course, 90% of why they don't (can't) do or become that is that those making the courses won/t or can't do it. Everybody works in isolation on their own small course(s).
