BBC Business English is suitable for anyone who has studied English to intermediate level or above, and who wants to use English at work. The book contains 24 units arranged in nine sections. Each unit contains a business topic, theme or problem. The companies, countries and characters involved change from section to section. This means that you can choose which unit to study, to review a particular skill or language point. You do not have to work through the book from unit 1 to unit 24, although this is a good way to use the materials.
