Free online courses, lessons and practice. You can learn anything.
Khan Academy is a nonprofit learning site that offers free lessons, short videos and practice exercises in maths, science, economics, computing and the humanities, from early years through to college level. Its strength is mastery-style practice: you work through exercises, get immediate feedback and revisit weak spots. It is widely used by students for revision and by parents and teachers as a supplement to school. Content is free to use, so the main limitation is that it offers no formal accredited qualification and is less suited to advanced specialist topics.
