Which reference book is better for class 7?r.d sharma or r.s agarwal

Nysa.... 
I think You must go for R.S Agarwal to prepare...........
Through this book , you will gain clarity of most of the topics as this book is more Efficient.

After you have gained confidence in the Subject... You can try RD Sharma then...(NOT VERY NECESSARY)

because RD Sharma is a bit of Higher level … So I recommend that book only if you are able to solve normal problems Easily...

Try your best to perfect with RS Agarwal first....

You will start loving Maths.

Best of Luck!

Rd sharma..

Fine?

Hope it would work!

Rs agrawala is also not bad
