Khan Academy allows you to learn almost anything for free.
Our iPad app is the best way to view Khan Academy’s complete library of over 2,600 videos.
We cover a massive number of topics, including K-12 math, science topics such as biology, chemistry, and physics, and even the humanities with playlists on finance and history.
Spend an afternoon brushing up on Statistics. Discover how the Krebs cycle works. Learn about the fundamentals of Computer Science. Prepare for that upcoming SAT. Or, if you’re feeling particularly adventurous, learn how fire stick farming changed the landscape of Australia.
Included in our iPad app:
- Downloadable videos: take individual videos or entire playlists to watch offline at your own pace
- Subtitles: follow along, skip ahead, or go back by navigating through subtitles
- Track your progress: Log in with your Khan Academy user account to get credit for watching videos, and see your achievements
- Exercises coming soon!
It doesn’t matter if you are 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. The Khan Academy’s materials and resources are available to you completely free of charge.
