Proficiency Writing Skills I is the first part of a two-part course which aims to teach the techniques students require to attempt any of the variations among the six forms of writing task set in the revised Proficiency examination. Approximately one third of the material in Writing Skills has been revised for this book. All the other material in this book is new. Eleven of the twenty units consist of two facing pages, and should, under normal circumstances, be completed in a lesson, with a writing task to be done later in approximately one hour, the time allowed for it in the examination. In the remaining nine units of four pages, two lessons will normally be required.
