Every miss becomes a scheduled review.
When you answer a question wrong, E.A.T. schedules it back into your queue at the interval the evidence says will move it from short-term recognition into durable recall. As you get questions right, intervals expand. As you slip, they contract. You never re-study what you already know — and you never forget what you got wrong.
