This is a very nice initiative from MIT that publicates free online course material to anyone.
Learn is always good, and for free IS AWESOME!

Free lecture notes, exams, and videos from MIT. No registration required.
MIT OpenCourseWare (OCW) is a web-based publication of virtually all MIT course content. OCW is open and available to the world and is a permanent MIT activity.
What is MIT OpenCourseWare?
MIT OpenCourseWare is a free publication of MIT course materials that reflects almost all the undergraduate and graduate subjects taught at MIT.
- OCW is not an MIT education.
- OCW does not grant degrees or certificates.
- OCW does not provide access to MIT faculty.
- Materials may not reflect entire content of the course.
How do I register to use MIT OpenCourseWare?
There is no registration or enrollment process because OCW is not a credit-bearing or degree-granting initiative.
Can I get a certificate?
No. MIT OpenCourseWare is a publication of the course materials that support the dynamic classroom interactions of an MIT education; it is not a degree-granting or credit-bearing initiative. However, you should work through the materials at your own pace, and in whatever manner you desire.
How do I find what courses are available? How do I search your site?
A site overview is available for MIT OpenCourseWare. You can also browse courses by department or use the advanced search to locate a specific course or topic.
High school students and educators should check out Highlights for High School.
What it takes to support this work
Each course we publish requires an investment of $10,000 to $15,000 to compile course materials from faculty, ensure proper licensing for open sharing, and format materials for global distribution. Courses with video content cost about twice as much, but your feedback about the significant value of these video materials helps to justify the cost. Learn more.
