This is not just a simple proofreading exercise book. It is written to fulfil the desire of those students who want to be challenged by a more difficult level of English grammar. Despite this, students with a lower English standard can also benefit. They can improve their grammar by doing the exercises and learning from the detailed explanatory notes which include ample examples to illustrate the correct usage of some difficult grammar and vocabulary items
(e.g. participles, parts of speech).
