The Extensive Reading Foundation aims to determine the reader’s general understanding of books read by the reader taking short quizzes contained on the M-reader site after the book has been read. The books are available in Arabic and cover several levels for different age groups. Available books are divided into two types; hard-copy books and e-books. Quizzes based on the books cover four questions categories, multiple-choice, who said, true or false, and order the events.
