The book has been intended to meet the necessities of the students who wish not only to score high marks in Grammar or any section of English but also to speak and write correct English; and correct English as I would like to think, is neither too free an informal style which challenges language structure nor excessively immaculate a sentence structure which won't, making it impossible to recognize idioms established by usage. It is, on the contrary, a happy fusion of the two, for even dynamic neutrality or peaceful co-existence is not enough. This book in your grasp is immensely useful for the applicants preparing for various competitive examination or need to realize what English is. After the end of each chapter, error spotting exercise is given which will be extremely useful for quick grasp & learning as well as in competitive exams. I will keep on making this book more exciting and more improved editions will be launched. A very special thanks to Pankaj Sharma and my family members who kept me motivated all the way.
