A word form is any spelling that appears in the text, so “walk” and “walked” count twice, and names count too. These numbers are a guide to how much vocabulary the book asks for, not a test. The level itself was set by hand by our team. Before you commit, read one page of the free edition and count the words you do not know: the one-page test takes two minutes.
