nidhi plz read dinesh madan only. Bcoz if u read munish valecha then kya likha he wahi pata nahi chalega.
And if u read dinesh madan then tumhara concept clear hoga and also ur confidence will boost up.
I also read dinesh madan book and diagram of isca in all chapter which provide by my coaching class. More than enough dinesh madan and for rapid revision diagram chat presentation is better.
This book is available in Hindi edition also. I have read this book. This book is exam oriented. This book is much better than other books in this market. Most of the topics in this book are discussed in points which r easy to remember. Hope this book might be helpful to all my club friends.
just go for manish valecha n if u hav tym tthen refer practice manual....i had done research as which book to b choose for isca..i haakready given 2nd group this tym n trust me manish valecha is sufficient ....nice book
