Founded by Harvard and MIT, edX is a popular online learning platform and nonprofit working to democratize learning. Obstacles like steep tuition and location are no longer barriers when classes are available online for free or for affordable prices.
The platform’s 2,500+ online courses are free to audit, and many of the courses are sourced from the world’s top universities, including MIT, Princeton, Yale, Columbia, Stanford, the University of Michigan, NYU, and more.
Of all the courses, about 145 are from Harvard — spanning subjects from public health and history to programming and poetry.
You can audit these classes for free or opt to pay $50-$200 for features like graded homework and certificates of completion that you can add to your resume or LinkedIn profile.
