With over 157K courses and 425 million enrollments, Udemy has become one of the largest online learning platforms in the world. We wouldn’t be surprised if Udemy goes public this year, just like Coursera who recently filed its S-1 form.

In an extensive analysis conducted by my colleague @dhawal, we found that 10% of Udemy’s catalog is free. Early this year, Class Central published a list of the 250 Top Udemy Courses of All Time, which included Udemy’s most popular courses, both free and paid.

This time around, it’s all about free content: we’ve put together a list of Udemy’s 250 most popular free online courses.
