I took this book to improve my basics in mathematics and to boost confidence to prepare for the jee entrance exam and i studied this book but due to 12th boards I didn't studied much and now the book is still in very good condition I have gone to many book store but they give so less price and says it's not needed them but i know a learner will always need this book it has detailed basics of every topic included in this I just hope that this book should be used not to just kept so plzz share and ask your child or their friends if they wanted to take this book 😇thank you so much 💗
