Free education! Where do I sign up?rnMillions of students are already signed up to courses offered by US start-ups Coursera, Udacity and EdX. Between them, the three sites provide courses from around 40 universities, including the Massachusetts Institute of Technology, Caltech and Harvard University. This side of the pond, the University of Edinburgh and University of London have started offering courses with Coursera, and the number of options is set to grow. Eleven other UK universities plan to launch free online courses with the Open University's new M00C company Futurelearn later this year.
