Flexible - the material can be used in any order, depending on students' needs. Clearly organised - the Contents list, internal cross-referencing and comprehensive Index helps students select the areas of study required. Easy to use - grammatical information is given in short, manageable amounts, immediately followed by practice exercises. Adaptable - each item is marked with one, two or three asterisks to indicate the relative level of difficulty. Authoritative - for students wishing to investigate as particular point in more depth this book is cross-referenced throughout to the Longman English Grammar. Enjoyable - the context exercise in each section is an entertaining story illustrated with a cartoon; grammar practice needn't always be serious!
