The book Indian Polity written by Laxmikanth Sir is the only book refered by all the UPSC aspirants preparing for civil service exams. Also it is useful for MPSC. It is the complete package of the detail explanation about our indian constitution. All the articles, amendment and policy of the government are properly explained in it. The most positive factor of this book is its simple and Lucid language.
All the serious UPSC aspirants, if you really want to crack the exam then you need to eat and feed it to your neurons. Atleast 3 times revision is must of this book before appearing in the exam. Direct question are asked in the exam from this book.
Please purchase the latest edition so that you get updated about the changes in the policy of government.
The book is costly in the market around 500/-. I would suggest you to buy it online from Amazon where it is available in 350-400/-
I hope this review clears the doubt and importance of this book among new UPSC aspirants, if any.
