Edx is a proven catalyst for the future of digital education with a global reach. The courses in "Professional Finance" with the University of Michigan, the University of Columbia or "Data Science" with MIT or Harvard University for example, are beyond reasonable doubt, outstandingly professional. Demonstrably, this "non-profit making platform" that survives partly from small donations, is on the verge of making quality education "historically affordable for all on the planet". Free thinking, Learning and innovation belongs to edX. "Good luck to you my brothers and sisters".John
