Having had the privilege to attend his lectures, I was not sure if his book would add any additional value, but I was wrong about my apprehension.
The book is neatly written for someone naïve in economics like me. The concepts are explained in layman language with appropriate examples wherever required, before you go on to take up hard books like Uma Kapila or a Dutt, this is a must read for every civil service aspirant. If you're good at inductive logic, you may not even need another book unless you have opted for Economics in Mains.
The book works for you even if you have a general curiosity to know about Indian Economy and some major events that have happened since independence.
