Study at the MIT for free
The MIT offers a selection of a few hundreds of its courses online with its OpenCourseWare program:
The idea behind MIT OpenCourseWare (OCW) is to make MIT course materials that are used in the teaching of almost all undergraduate and graduate subjects available on the Web, free of charge, to any user anywhere in the world. MIT OCW will advance technology-enhanced education at MIT, and will serve as a model for university dissemination of knowledge in the Internet age. This venture continues the tradition at MIT, and in American higher education, of open dissemination of educational materials, philosophy, and modes of thought, and will help lead to fundamental changes in the way colleges and universities utilize the Web as a vehicle for education.
One cannot graduate or pretend to have got an MIT education with it, nevertheless, this is a great initiative.
