What's Khan Academy All About?
Learn almost anything for free.
With a library of over 4,100 videos on everything from arithmetic to physics, finance, and history and hundreds of skills to practice, we're on a mission to help you learn what you want, when you want, at your own pace.
We are a donor-supported not-for-profit and would not be possible without the generous support of users everywhere. In particular, we'd like to thank our major supporters for their strong support of our mission.
