I had bought this book when I was in class 11. In the beginning, I liked it alot. I had bought this book for the preparation of board exams. It includes all the chapters related class 11 and 12. It is divided in two parts. I was very happy by seeing the chapters. But I went to contents, I felt it quite difficult for me. Many of the topics were related to jee mains and advance exams. It has many questions in every chapter. The topics which were beneficial for me, I read it and I found a liitle bit difficulty in understanding to the concept of the topic. After weeks, I have consulted to school teacher and he recommended me to read another book named Physics GRB . And after the completition of this book, I should read this book and solve all the questions. I did it same as advised by my teacher and I got positive result also. Then, I understood that this book is tough to read and it is a high level book for the students like me who are preparing for the board exams only.
