It is a great book. I bought it 2 months ago, when I started preparation for the Govt Exams. This book was suggest by my aptitude teacher from a renowned coaching institute. And after going through it I was satisfied by its content. It will also help you in your preparation for other exams which has aptitude paper in it. If you are a CAT and a bank PO aspirant I will suggest you to go through this book 1st and then you can go for Quantitative Aptitude by Arun Sharma. I have myself cleared the ibps PO prelims exam and waiting for my mains result! So buddies all the best and always remember that there is "NO SUBSTITUTE OF HARDWORK"
