About this app

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)!

So far so good. Brushing up and refreshing my memory on topics I studied when I was younger. One thing I like is the game aspect of it. You get rewarded when completing the lessons. One thing I would like for you guys to add is a green check mark on the course icon when a course is 100% complete. On the app, if you look at the course list, there's no indicator on which you completed. Example, I'm going to do all math, from early/kid to high school. I'd like to see the grade levels checked off.

the content is so good, but the content navigation is so confusing, too many categories, too many different ways to study the same content. there should be a simplified way of ordering the content, I remember back in 2013 when the math content was so straight forward, now it is such a convoluted, humongous, overwhelming, neverending path that it becomes hard to bare, and I find myself discouraged to even attempt to resume my learning

That is some lazy writing on the developers part if you aren't "able" to track more than 9 courses at a time. This means I can't layout my path without going in to edit and moving them around as I go. Stupid, limiting in more ways than one, and not worth my time. Clearly the online desktop version is the only one partially worth my time and effort.
