Strengths and weaknesses
Khan Academy
- Core lessons and practice are free, with no ads
- Practice adapts to what you have and haven't mastered
- Excellent for school math, from basics to calculus
- School-style format can drag for adult learners
- Arts and humanities coverage is thinner than math and science
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.

Quizlet
- Huge library of ready-made sets for common classes
- Several study modes keep review from getting stale
- Very quick to create and share your own sets
- Free plan has ads and limits Learn and Test modes
- User-made sets can contain mistakes
Quizlet is the quickest way to turn class notes into flashcards, and its huge library of shared sets means someone has often made yours already. Learn mode, matching games and practice tests keep review varied. The catch: the free plan has ads and limits the best study modes, and shared sets can contain errors. Great for students reviewing for school tests.
