The "Grammar Booster" series has been carefully researched and planned for beginner to intermediate students who need grammar practice. The key features include: grammar points are taught in short, easy stages which students can easily cope with; a wealth of exercises after the presentation of each grammar point gives plenty of practice of what has been taught; clear and simple explanations of all the grammar points covered encourage students to study alone and gain a better understanding of the material; a communication activity and a writing task at the end of every unit consolidate the grammar points covered in each unit in a fun and effective way; five review sections ensure that students have a thorough understanding of all the grammar points covered in the previous units; and, five progress tests give teachers the opportunity to assess their students' progress. Also available are a teachers Book, test Book and CD-ROM.
