Each book in the series focuses on a separate skill. This allows students to concentrate on the necessary techniques and strategies typically related to developing that skill area and improving skill-related scores on standardized tests of English for that particular skill. Each level of the series targets 500 different headwords so that students completing all four levels will be able to study 2,000 different headwords. Used together, the books provide a complete learning experience for developing students’ English language abilities across the four fundamental skill areas.
