The best book I have seen in my life. The way, the methods, the clarity is most understanding and of course I prefer this book to everyone to be in successful in most of the competitive exams and also for people who intend to get a job in their college placements. For the first time when I bought this book, and started practicing the methods I found that I am totally addicted to this book and keep other’s material aside which makes me more and more comfortable to the maths and with ultimate shortcuts, the speed of solving to me is reduced from time to time. I obviously like most important thing in this book which is a question contains answers in quicker methods and shortcuts - I loved it.
