MIT OpenCourseWare (MIT OCW) makes the course materials that are used in the teaching of almost all MIT’s undergraduate and graduate subjects available on the Web, free of charge, to any user anywhere in the world.
MIT OCW is a large-scale, Web-based publication of MIT course materials, and is not a degree-granting or credit-bearing initiative.
MIT OCW would not be possible without the support and generosity of the MIT faculty who choose to share their research, pedagogy, and knowledge to benefit others.
