I am totaly disappointed when I open the book the cover and packing looks so nice but when I opended the cover I m shocked after seeing the pages the qualty of page used in this book is realy very bad and I order this book after seing my friend book that was very nice nd quality of the page is excellent nd.have Colored index page but mine do not have. Also this book is very old with the increasing level of competitive examinations, the book does not make a candidate ready to take the exams
