So far, having finished two certificate programs offered by a renowned university through this education platform, I am very pleased with the frictionless service offered. The profile validation and payment processes were quick and without headaches. I would point out though for the edX to consider the following: throughout the day I utilize at one point or another each of my laptop, tablet and smartphone. I have had difficulty syncing my progress made using each of these devices with one another. All in all, so far so good.
