edX is an online learning platform best known for offering a wide variety of courses, from free courses to full degrees. It was founded in 2012 by professors from Harvard and MIT as an experiment to make the world’s best education. Its courses and programs are designed in partnership with top Universities and Organizations to help learners launch and excel their careers.

The platform’s courses and programs are often instructor-led and come with designated start and end dates. Many of its courses you can access for free following the Audit Track, but this will come with certain limitations, and you won’t get access to all the features. Alternatively, you can pay for the course opting for the verified track, which means you’ll receive a certificate upon completion and access to graded assignments and exams. edX also offers a plan for businesses, which are custom-curated and tailored to the specific needs of your team or organization.

With edX, each course or program is individually paid for, there are no subscription plans available, and if you do change your mind, a 14-day refund policy is available. A great way to get started with the platform is by checking out one of its free courses.

The courses in the list below are free to audit — that is, you get access to the course materials for a limited time, but can’t access graded assignments and exams, and don’t receive a certificate of completion.
