About edX
edX was founded by MIT and Harvard and offers university courses at the highest level. Nearly everything can be audited for free; you only pay if you want a verified certificate. The catalog is more academic and deeper than most platforms, with real university subjects in computer science, economics, and the sciences. For anyone who wants depth without tuition fees.
“Nearly everything can be audited for free at MIT and Harvard level: that remains remarkable. The academic approach takes discipline, but the depth is unmatched.”Editorial team, via CourseShortlist
