One of my favourite English language practice books. Comprehensive, authoritive, good, structured approach to presenting an overview of the English language for both those who love the language and those seeking to aquire it. Practical format with explanation of topic on left hand side and practice exercices on the right page. Chapter and exit test as well as CD also very useful. Great aid to get my students back on track when they lost the plot in the jungle that the English language can sometimes appear to be.
