I am currently studying A-Level English at college. I originally borrowed this book from my tutor to help me with my work as I was having problems when it came to literary analysis. The book goes into great depth in explaining the rules of English Grammar and its complexities in a clear and concise format, which I personally found easy to understand. I have read and used other books as a point of reference, such as 'Grammar Structure and Style' by Shirley Russell but I found that they were too complex to use as a quick tool and although the latter is another excellent book, when it comes to ranking them for ease of use, the book by Shirley Russell does not even come close. I would recommend this book to anybody who is having difficulties with English grammar or anybody who simply wants to correct the grammar that they use in day-to-day life. This book is also useful for those who are learning a foreign language and are having difficulties in relating the grammar of the new language to that of their own. This is something that I have experienced first hand. Overall, I would recommend anybody who wants help with grammar to purchase this book as it is one of the best that I have seen.
