So I bought this book few days before my SSC CGL 2019 examination. Honestly speaking this book is excellent for a quick revision before examination. Though there are a few mistakes in the book but I'd definitely recommend this book for all the students who are just starting their preparation for any competitive exams. This book is to the point and concise. Once you are done with this book then you can go further for any gs book like Lucent etc.
I got this book delivered today and the first thing looked was current affairs section. Most of which were outdated, misprinted or wrong. This is a 2020 edition and thought Arihant publication to be reputed but the who's who section is totally wrong. It is printed that Nirmala sitharaman is defence minister and Rajnath singh is the current home affairs minister. Great!! CAN I TRUST THIS BOOK? OBVIOUSLY NO.
This book just updated the current affairs portion.. only 28 pages of 128 pages are updated version... Others 100 pages is the copy paste of the same thing. Word by word matched. So if you have a previous version then it's better to go for a current affairs book except this.
