Does it deserve #1?
The verdict
Khan Academy is the best free learning resource you can install. Clear videos and mastery-based practice cover math from arithmetic to calculus, plus science, economics, grammar and computing. It is run by a nonprofit, so there are no ads and no core lessons behind a paywall. The catch is a school-like format that can feel dry for adults. Get it for yourself or your kids.
- Mastery-based practice exercises
- Math from arithmetic to calculus
