Components

Student’s Book
In the Student's Book, learners study the grammar in a realistic text and through corpus-informed charts and notes. The exercises provide practice in reading, writing, listening, and speaking. Students learn to avoid common mistakes, based on a corpus of learner language. Each unit concludes with a 'Grammar for Writing' section, in which students apply the grammar in an extended writing task.
There are also Split (A and B) versions of the Student’s Book.

Workbook
In the Workbook, learners gain additional practice in the grammar from the Student's Book, including practice correcting common learner errors. There are Split A and B versions of the Workbook for shorter courses.
