I m preparing for UPSC ( IAS) exam since last 6 months and I found this book- Polity by M.Laxmikant very useful.As many IAS institute always suggest for this book and every year more than 12 direct question came from this polity book Only in Polity subjects.
As the concept given in this book are in good manner and language is also simple so there is no difficulties to read it. As this book is available in Hindi as well as in English language.
MCQs are also provided in the last of the booklet to help the students so that they can familiar with the questions came in Exam.
Just Read this book two three times before the exam , it will help u more in clearing the concepts and many more related to polity subject and also it make polity easy for us.
