The book is very good for children . It's 80% of concepts are unused in class 7 and those 80% are in class 8 . It helps get future ready before reaching other class so we can also use this book for class 8 as well as I have started doing it from December 2020 when i am in class 7 and it would be easy for me to complete it till mid of class 8 .
