No support offered - out of date/incompatible materials issued to complete courses.Unfortunately this is the official provider of a course that I want to complete and there are no other options available. I am now 8 units in and have faced multiple issues with the course content being incompatible with environments that they have issued. Contacting EDX results in "we can't help you, ask others taking the course or fix it yourself and if you go past our quarterly mandated renewal window you will have to pay another $99". Not sure why they have to re-issue the course every 3 months given that all materials are the same again, think it may have something to do with it costing $99 each time(!)I would not recommend this provider to anyone, I wish I did not have to use them myself. Having used various providers previously for learning I can say this is the worst so far.
