The ProZ international translation bureau recommends this book with the HIGHEST (5) rating > Whether you want to learn or to teach the correct use of English Grammar, this book will make it very easy for you. If you are a native of an English speaking country but not sure, for example, about the proper use of the Tenses, you will be amazed when you see this method quickly clearing up any confusion you might have. If English is your second (or third, etc.) language, you may have difficulties comprehending when and why you need to use certain forms of grammar, especially if your native language does not even have that form. A good example for this is the use of Past Tense in the Hungarian language where the English "to be" is expressed only by the word "volt" while the English language has three different ways to form the "to be" in the past ("had been", "was or were", "have been or has been"). Give this method a try, you will not be disappointed.
