Scores come from the same vocabulary the Btelo English app teaches, so the ladder matches the order the app introduces words in. Fairy tales and adventure stories sit at the top; Shakespeare, written in Early Modern English, sits at the bottom — a modern learner meets thou, thy and hath on the first page.
