On viewing the pattern of many DNB/NEET Exam patterns, I felt that there is no book available in the market for the best preparation to crack the exam by saving time of aspirants. Many of the exams had repeats all the time. This book is started with sole purpose of clearing various aspects of statistics and guide aspirants for their preparation. For controversial question every attempt has been made to trace the source and solve the questions. I would like to concentrate all the contributors for their commitment and hard work.
