Really great book!! The problems chosen in the book are one of most challenging and thought provoking. A good conceptual understanding is abosolutely essential to solve these problems and book talks about all the concepts required to solve the problems. One of the most fascinating aspect is how the author has introduced the solution using first principles and defintion of the concepts themselves. The solutions are elegant and open up one’s mind to approach the problems in different ways. With the time in hand during the exam, honing and finding the best approach to a problem is absolutely critical and this book delivers that promise. Highly recommend this book to anyone whoever is preparing for JEE.

Thank you!
