This is one of the famous book for govt jobs every student preparing for govt exams knows about this book. It is the first choice for every student in maths. But I want to highlight some problems that I saw in this book is that the book do not update itself according to current syllabus in govt exams. This book last update on 2004. After 2004 many patterns were changed in exams. Please update this book so that students will benefited.
