What's Khan Academy All About?
Learn almost anything for free.
Our mission is to provide a free, world-class education for anyone, anywhere. All of our resources are completely free forever, regardless of whether you're a student, teacher, home-schooler, principal, adult returning to the classroom after 20 years, or a friendly alien just trying to get a leg up in earthly biology.
We're a 501(c)(3) nonprofit, and we would not be possible without the generous support of users everywhere. In particular, we'd like to thank our major supporters for helping our mission.
