When I was in 9th class my I was very interested in mathematics .i finished my shool mathematics book in almost two or three months.then , my maths teacher prescribed me to purchase R D SHARMA for mathematics it contain a lot of no. Of question and deep knowledge of concept.then , forst time I tried the book and now I am in 12th class and I am still using it .i bave a collection of it for every class from 8th to 10th
It is very good for those students who enjoy match amd try to solve a huge no. Of questions .this is a holy book for them
