I would like to give my opinion on the book Xam idea .
I am very happy from this book because it has a clear cut view of a chapter in the form of a flow chart .
It covers all the basic concepts of science about each and every topic and also contains value based questions which are very heplful for scoring marks in the cbse class 10th examination.
The language of this book is quite simplified and easy to understand .
It also contains previous year solved questions which are very helpful in exams.
I think it is the best book for studying for exams .
I would recommend others also to go for it.
