Academic & Study Help - Free Channels to Learn Any Subject

Khan Academy is the closest thing the internet has to a free school. It is a nonprofit, which means there is no course to buy, no membership, and no upsell waiting at the end of a lesson - just thousands of short, step by step videos covering math from counting through calculus, plus science, economics, and test prep. Every topic is broken into small pieces you watch in order, and the whole thing is built to take you from not understanding something to understanding it. If you or your kids are stuck on a subject and need a patient teacher who never rushes, start here.

CrashCourse has spent over a decade making free, fast-paced courses on nearly every school subject - biology, chemistry, physics, history, and literature among them. Produced with backing from PBS, it is genuinely free with no course to buy and no signup. Each series walks through a full subject in short, energetic episodes that make hard material stick, which makes it perfect for a student who needs the big picture before an exam, or anyone who wants to finally understand a subject they slept through in school. Pair it with the step by step channels in the subcategories when you need to work actual problems.
