Got redirected to the coursera site from microsoft cloud certification site. Despite the course tag being 'Enroll Free' there was a convoluted sign up that asks for your Credit Card details all with the intention for you to sign up for 1 month and forget to cancel, which I did. The 'free' course cost be 60 Dollars, its little more than a way of getting a month's subscription for you. Even the course is poor - all videos, no grahpical explanations, DON'T BOTHER WITH IT.
