When I was doing my preparation for PG Entrance Examination, I myself realized that many of the upcoming exam questions are asked from last year paper. So, I remained very curious to find authentic book of previous year paper. Many times book contains wrong questions, wrong answers or too lengthy non-specific explanations. In this way I find very depressed to myself. And I always thought that there would be a best book on previous year paper. It now gives me immense pleasure to share this book with all possible questions with best possible explanations. This book is written in such a way that it can be completed in a very short time with retrograde manner. The book covers all possible MCQs of previous year exam. Its explanation is a handy reference for those who are preparing to appear in postgraduate entrance examinations and it gives a comprehensive, brief and yet lucid account of subject. Please remember I have given the best effort to this book and hopefully you will find all relevant theories in this user-friendly book.
