This book was written to overcome the difficulties faced by medical students since thu Single Best Answer Question pattern was introduced to the medical curriculum globally. The first edition was produced to help the students understand the style and the method of answering SBA questions as hitherto there was a dearth of standard model question paper books. It contains the relevant clinical principles and knowledge required to answer SBA questions and detailed explanation for the answers. The first edition had unprecedented large sales and the author was invited to write the second edition after two years.
