The Feynman Technique: How to Revise by Teaching It Back
If you can't explain it simply, you don't understand it well enough. That idea sits at the heart of the Feynman Technique — a deceptively simple revision method named after the Nobel Prize-winning physicist Richard Feynman, who was famous for making fiendishly complex ideas feel obvious. For students revising for GCSEs and A-Levels, it's one of the most powerful ways to turn vague, half-remembered notes into genuine understanding. This guide explains exactly what the Feynman Technique is, why it works, and how to use it for any subject — without wasting hours. What Is the Feynman Technique? The Feynman Technique is a four-step method for learning something so thoroughly that you can teach it to a complete beginner. Instead of re-reading your notes and hoping the information sticks, you force yourself to explain the topic in plain language, spot the gaps in your own understanding, and fix them. The four steps are simple: choose a topic, explain it as if teaching a child, id...
