In this second edition, you will find 3 mock papers. Each one contains 100 questions in a Best of Five (BOF) format. Self-assess, try to complete each paper within 3 hours, check out your answers, read the explanation, and re-read accredited medicine textbooks to fill in the gap in your knowledge. Each question has an "objective"; try to review what the objective is about. This is the only self-assessment book specifically written to imitate the MRCPI part I examination. Each mock paper in the first edition of this book contained 50 BOFs and 50 MCQs formats. The Royal College of Physicians of Ireland states that the MRCPI General Medicine Part I examination consists of one paper with 100 Single Best Answer (i.e., best of five) questions. You have three hours to complete the exam. There is no negative marking and each question is equally weighted. Single Best Answer questions consist of a "vignette" (clinical scenario) followed by five possible answers. You must select the single best answer. Good luck!
