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)!

Amazingly Helpful

As someone who is studying from home, this app has helped me in so many ways. Truly thankful for it. Maybe soon you can incorporate a “highlight” feature too? So I can highlight the notes and it will still be there when I close the app and open it again.

Developer Response ,

Hi, there! While we do not currently offer a highlight feature, please know that we continue to add new features to improve the experience at Khan Academy. I encourage you to share your request in our discussion forums (http://khan.co/KA-community), where users can add their thoughts to yours and vote on your suggestions. Thank you!

This app is my high school.

I literally slept through my entire high school and still managed to get a GPA around 3.8. I simply used the app to learn whatever is in the syllabus a day before my exams. I highly recommend using this app as it teaches much better than my high school.
