For each collection there is a Student’s Book without answers, Student’s Book with answers, Audio CDs and a Self-study Pack (Student’s Book with answers + Audio, which for First 1 comes in Audio CDs and for First 2 is a downloadable file). The Student's Book with answers and Self-study Pack contain the answer key and recording scripts, making it ideal for self-study or classroom use.
