It’s a my honest review. I used to read this book from 9 to 12th class. it’s a good book to make your math’s concept strong.The level of this Book is best for board exam but this book is not good for jee main or jee advanced if you want to get a good rank. but the objective book of rd Sharma is good for main and advanced. I completely slove 12 or 10th rd Sharma book and I got 98 marks in 12th and 100 marks in 10th. most of the question which are coming in board exam are same like rd Sharma’s book questions. I didn’t prefer any other book except rd Sharma’s .
