Whether you enjoy learning, investing in your career or preparing for college, you should take a look at the edx.org course offering: 300 free courses, most of them created by top universities.
In the last three months, edX has launched over 100 courses, many of the them inside the High School Initiative (disclosure: IBL is filming two of them, for the Cooper Union). The 300th course was announced last week.
Congratulations edX!
