Tense Buster, Clarity’s most popular program, helps learners develop their confidence with 33 key grammar areas from the simple present at Elementary level to phrasal verbs at Advanced. The program is ideal either as a self-access resource, or integrated into a course of study and used in class or for homework.


The Tense Buster syllabus, available here, follows a logical progression from Elementary level (A2) through to Advanced (C1) that mirrors the coverage of most international course books. Within each unit, learners both encounter and use the target language in a variety of text types from radio broadcasts to quizzes to newspaper articles. Each unit includes both controlled practice exercises and freer activities to do away from the computer.


Grammar in context. Each unit begins with a presentation based on a dialogue, story or interview, where learners are encouraged to form theories about how the grammar works.
