Ask a class how they revise and you'll hear the same three answers: re-reading notes, highlighting, and copying things out. They're the most popular revision strategies in the country, and among the least effective. They feelproductive because the material feels familiar, but familiarity isn't memory.
What actually works
1. Retrieval practice
The single best-evidenced revision strategy: close the book and try to pull the answer out of your head. Every successful retrieval strengthens the memory far more than another read-through. It's the same principle behind mini whiteboards in lessons: committing to an answer beats nodding along.
2. Spacing
Three twenty-minute sessions across a week beat one hour the night before, every time. Forgetting a little between sessions is the point: re-learning something you've half-forgotten is what makes it durable.
3. Low stakes, high frequency
Little-and-often quizzing with instant feedback builds knowledge without the anxiety of a big test. Wrong answers are information, not failure. The sooner a misconception surfaces, the cheaper it is to fix.
The problem: doing this alone is hard
Retrieval practice needs questions. Spacing needs a schedule. Feedback needs someone (or something) checking the answers. Asking a teenager to build all of that with a highlighter and an exercise book is asking a lot.
That's exactly what Revision Genie is for: free question-based revision from KS2 and KS3 through GCSE and A-level, built around retrieval and spacing so students don't have to engineer it themselves. Built by the same team as AnswerBoards, and free in the same spirit.
For teachers: close the loop
If your boards-up momentshows a gap today, the highest-value homework is one sentence: “Tonight, revise that topic on Revision Genie.” Then open tomorrow's lesson with boards up on the same question, and watch the gap close.
