EdX is a massive open online course(MOOC) provider. It hosts online university-level courses in a wide range of disciplines to a worldwide student body, including some courses at no charge. It also conducts research into learning based on how people use its platform. EdX differs from other MOOC providers, such as Coursera and Udacity, in that it is a nonprofit organization and runs on open-source software.
I have personally taken atleast 5 courses @ Edx, and I am deeply satisfied. The courses are well structured and it feels like a real classroom. The teachers are excellent.
The certificate is a valuable one and the price depends on program to program.
You wouldn’t be disappointed!
