MIT OpenCourseWare

MIT OpenCourseWare makes the materials from real MIT courses available free to anyone with internet access. You'll find lecture notes, problem sets, exams, and sometimes video recordings across engineering, science, mathematics, economics, and other subjects. There's no enrollment, no prerequisites to check, and no certificates at the end.

This is ideal for self-taught learners who want genuine academic rigor and the chance to see what MIT-level coursework looks like. Students preparing for advanced studies, professionals brushing up on theory, and curious learners all find value in the depth and quality of MIT's materials.
