Khan Academy

The Khan Academy is a not-for-profit organization founded by Salman Khan with the mission of providing a high quality education to anyone, anywhere. It is currently a library of 1400+ videos on YouTube (and mirrored elsewhere) covering everything from basic arithmetic to advanced calculus, chemistry, economics and biology. The videos are supplemented by software that dynamically generates exercises and captures data on student usage and progress.

Salman Khan received his MBA from Harvard Business School. He also holds a Masters in electrical engineering and computer science, a BS in electrical engineering and computer science, and a BS in mathematics from the Massachusetts Institute of Technology.

The entire video library (it will blow you away!) can be accessed at The Khan’s Academy site.

Not just FREE (woo hoo!) but really excellent material, ma shaa Allah.
