Description

You can learn anything. For free.

Spend an afternoon brushing up on statistics. Discover how the Krebs cycle works. Get a head start on next semester's geometry. Prepare for upcoming exams. Or, if you're feeling particularly adventurous, learn how fire-stick farming changes the landscape of Australia.

Whether you're a student, teacher, homeschooler, principal, adult returning to the classroom after 20 years, or a friendly alien trying to get a leg up in earthly biology — Khan Academy's personalized learning library is available to you, for free.

- Learn anything, for free: Thousands of interactive exercises, videos, and articles at your fingertips. Study math, science, economics, finance, grammar, history, government, politics, and much, much more.

- Sharpen your skills: Practice exercises, quizzes, and tests with instant feedback and step-by-step hints. Follow along with what you're learning in school, or practice at your own pace.

- Keep learning when you're offline: Bookmark and download your favorite content to watch videos without an internet connection.

- Pick up where you left off: Tailored to your current learning level, our mastery system gives instant feedback and recommendations on exactly which skills and videos to try next. And, if you choose to create a free account, your learning syncs with http://khanacademy.org, so your progress is always up-to-date across all your devices.

Learn using expert-created videos, interactive exercises, and in-depth articles in math (arithmetic, pre-algebra, algebra, geometry, trigonometry, statistics, calculus, differential equations, linear algebra), science (biology, chemistry, physics), economics (microeconomics, macroeconomics, finance and capital markets), humanities (art history, civics, finance, US history, US government and politics, world history), and more (including computer science principles)!

I love khan academy. It has helped me with some college courses and now I use it for personal reasons. It has great content and all for free. My only issue is that sometimes when I open the app all I get is a white screen and I have to close it and reopen it.

Awesome!
