overall its nice book..covers the new syllabus too n have some similarities with old kvs madan book.. i have read only 2nd unit (research) of this book till now.. n there is mistake in practice question's answer keys(no. series are not in order)..dont know about other units..
This book is a base book to clear basic concepts..... I'm referring kvs madaan from its 1st edition even recommend my students also... This time it is little broad and updated.... Few topics need little updation..... Overall I prefer this book over all other
The book covers the breadth of the syallabus in a brief manner. There are sufficient practise questions and I'm sure it will be sufficient to score well in the exam. However there are some errors in the questions and the answers though these are not many they can be misleading for aspirants. On the whole one of the better comprehensive books available books in the market. Can come very hand for last minute prep and revision.
