Given what it offers and the fact that it's entirely free to use, Khan Academy is the best learning site for academic subjects and an Editors' Choice pick. Support for more languages is in the works. In other words, you can take Algebra I taught in Spanish rather than English. It does, however, offer its courses to speakers of other languages, namely, Spanish, French, and Brazilian Portuguese. There are some small gaps in the content catalog Khan doesn't offer classes in music, music appreciation, or foreign languages, for example.

In July 2020, the site announced it would concentrate more acutely on kindergarten through early college courses and was thus retiring materials that fall outside that scope. The lessons contain videos, readings, and interactive components, which are sequenced so that you can start from square one with any subject and slowly build your knowledge. Khan Academy is a free online learning service with course material covering math, science, art history, and other subjects. Where can you go online to learn-not just learn to solve an immediate problem, but advance your understanding of a topic or start studying something from scratch? For most academic subjects, the best place is Khan Academy.
