MIT OpenCourseWare review

MIT OpenCourseWare is the deepest free source of university course material on this list. It publishes notes, assignments, exams and videos from 2,500+ MIT courses covering the entire MIT curriculum, and says it has reached 500 million+ learners and educators. There is no enrollment and no account, and courses have no start or end dates, so you can open a physics or computer science class and work through it at your own pace. Materials can be downloaded, shared, modified and reused as long as you cite MIT OpenCourseWare. OCW is now part of MIT Learn, a hub that brings together OCW, MITx and other MIT learning options, which helps if you later want a graded course. The trade-off is clear on its own about page: MIT does not offer credit or certification to OCW users. You get no grading, no feedback and no deadlines, so it works best for disciplined learners or as a companion to a paid course.
