There are two language reviews. Each review consists of 100 grammar questions, which revise the grammar of the previous five units, and 50 multiple-choice vocabulary questions also based on the previous five units. The writing reference section provides students with guidance on writing emails, formal letters, faxes and brief exam-style reports. The section includes a list of essential phrases useful to students not only in the examination but also in their professional lives. A full answer key is provided at the back of the book.
