What a wonderful book.

I joined tuition classes in April. I read Hc Verma. I read Resnik Haliday Walker. I solved the package. I was confident. After learning problem solving for three chapters from this book I felt I was nut. I learnt many concepts and techniques from this book. All the solutions are gem but many are out of the world. This book is for for better than any book for IIT JEE. Thank you Professor Neelam. Great work Sir.
