Hi,
Generally there is a problem with ncert books that the content which is written is not in detail and also the language is not easy to understand . So one thing you can do is search the summary of that particular chapter from any website and read thoroughly until you get a clear that what's inside that chapter then you can go for reading the whole chapter from ncert . Otherwise you can purchase guide books they are in detail and the language is easy to understand .
Hope it helps...

Dear student,

NCERT is one of the most simplest and conceptual book available to students.
NCERT book is very easy and anyone can understand this book very easily. The language is very simple, so, if you read each and every line you will develop a particular interest and you will start to understand the language.
Basically in ncert books the concepts are hidden in the lines of the paragraphs and that's why many mentors say that first read each and every line of ncert book. And in reality too, for understanding the concepts you have to study each and every line of that book with interest, and after that solve the examples and the given questions.
