I used Coursera to complete three courses. All courses on the website are created by universities. Coursera never asked me for my card details and I was never charged for anything, except when I chose to purchase certificates after completing my MOOCs. I was not charged for any subscriptions, or anything other than the three certificates I bought.The website and app are easy to use. I never had any issues finding a course or completing one. There are discussion boards to ask questions and interact with the professors of your courses.I’ve been using several sites to help build my CV and Coursera is by far the best. Everything is genuine and created by institutions you can trust, and you don’t have to pay for anything. It was easy to learn from Coursera, and I’m much more knowledgeable in the field I am trying to start a career in as a result.
