There are many books available in the market but this is the true gem among them.
This book is one stop place where everything related to English or Verbal Ability is available.
From Vocabulary, Grammar, Idioms to Reading Comprehension this book stand out each department.
With 6 parts, 28 chapters and a lot of exercises after each chapter this book is arranged in a very good manner according to subject wise topics.
And every chapter first explains a particular thing and then gives a lot of questions to practice and more importantly it gives explanation as to why an answer is right or wrong.
So I recommend this book to every person preparing for any exam that has Verbal Section in it.
It is specially good for SSC and IBPS exam because it seems like it is designed for that purpose.
