There are books at three levels of difficulty from beginner to intermediate, suitable for use on their own or in support of a general coursebook. Within each chapter, grammar rules are taught in stages. Exercises follow each stage to check understanding.
Each student's book is accompanied by a teacher's book. This describes the features and organization of the student's book and gives answers to the exercises.
