Vocabulary and grammatical structures have been carefully controlled and graded over the three levels of the series to allow students a comfortable progression from easily accessible readings to more challenging readings. Exercises in the series have been designed to practice reading and comprehension skills useful for students interested in test-taking strategies. Reading Challenge is suitable for both classroom use and self-study, although students in the classroom will benefit from the additional activities presented in each unit focused on developing speaking, listening, and writing skills.
