(MIT OpenCourseWare) Free courses from the Massachusetts Institute of Technology. In 2003, MIT first published on its website the course materials from 500 graduate and undergraduate courses in 33 disciplines, including all the sciences as well as arts and humanities. Included are lecture notes, syllabi, problem sets and solutions, reading lists, exams, even video lectures in some instances. Notably excluded is access to the MIT faculty. Anyone can take a course without registration or qualification requirements, but MIT gives no credit for their satisfactory completion. For more information, visit http://ocw.mit.edu.
