This brand new MCQ publication is to be used in preparation for the MRCS examination. It reflects the current requirements of the examination, particularly addressing the fact that a large proportion of the questions relate to basic science topics; as well as addressing the new style question that the examination incorporates, the extended matching question (the EMQ) which tend to be very clinically based. Thus, the questions in this book are all based on clinically related subjects and on pure and applied basic science in proportions which reflect the content of the examination.
