Hello friends I am an aspirant of ssc cgl right now I am working in a government department which I got through the ssc chsl 2014 and the books from kiran publication helps a lot in cracking my ssc chsl in my first attempt.As I told you that now I am preparing for thethe ssc cgl, this book having a collection of previous year question papers proves quite helpful for clearing the tier 1, as it contains the detailed solution of the questions previously asked so that you dont have to waste your time in looking for the solution. But keep in mind that this book works for you only if your concepts in maths and English are clear and all you need is to practice to increase your speed and accuracy.Though with the change in the ssc mode of examination which is being conducted online now its importance slightly comes down but still you can take this offline mode alongwith the online practice set provided by different websites it will definitely help and you will be prepared for other exams that are still being conducted in offline mode.
