Hello friend’s
I am using Rd Sharma sir book since I am in 9 standard .
In his books there are so many questions to practice . I am big fan of this book. If student is fearing about maths then I should recommend this book , because in this all concept are clearing very sharply there are so many examples to practise if you solve examples a confidence will be up in you and the fear with will also start becoming low. In exercises also also questions are setup as from low to high. And I am thankful to this book.
