Wonderful

Top-notch teachers, a wide variety of courses, good productions values, and all absolutely free. The teachers really care about presenting material in a way that engages, enlightens, and entertains. Ive taken several courses here (and at edx.org, another great MOOC site that doesnt have an app, but works well with the iPad), mostly in science and philosophy and Im very pleased.

Try it, youll like it!
