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.

- 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.

Mostly good. The lessons are digestible and mostly straight forward, but the speaker tends to not explain certain things (often simple things I admittedly should know.) Sometimes I get frustrated getting questions wrong and ask for hints only to find that I was marked wrong even though I got the answer right verbatim to the hint. If not for these flaws it would be perfect!

Absolutely love the app, but one complaint. I am on my phone, and even though I am in landscape, when I am on the app it keeps rotating incessantly. I struggle to even watch the videos without the rotating tarnishing my experience. Please fix this, or tell me how to disable the rotating features. Thanks.

It's pretty good but.... I wish their was an option to have it read things out loud to the kids, like a little speaker button so it's optional. It would really help my kiddos and me. So far he can only do math on his own unless I can sit and read it too him, which isn't always an option. Also the patent dashboard needs an easier layout. I would also appreciate the option for a 4 digit pin for my kids to log in. And make the app on chromebooks work better. Other than that we love it!
