Touchstone, together with Viewpoint, is a six-level English program based on research from the Cambridge English Corpus. Each Student's Book contains approximately 90 hours of material across 12 topic-based units - with additional grammar and pronunciation practice added for the Second Edition. Student's Book, Level 4 is at the intermediate level (B1-B2). This version of the Student's Book also contains an activation code that grants access to the Online Workbook, Level 4 for 12 months. The Online Workbook provides practice of the language studied in the Student's Book. Exercises are graded automatically and students can easily track their progress and scores.
