Multiple choice questions make up an important part of the MRCS Part 1 examination. QBase Surgery: 1 is much more than just a book as it also comes with a free CD-ROM. This powerful electronic package is installed easily and gives the reader a huge range of options to greatly enhance the value and utility of the book. Not only can the reader practice the set exams, but the CD-ROM will mark these exams, allow the reader to customize exams to focus in on areas requiring further revision, shuffle the stems to in effect set an inexhaustible number of different papers, and advise on examination strategy. It has the facility to print out and store the results and provide helpful notes on each question. This version of the QBase software (termed QBase+ for this title) has been modified to analyse the non-negatively marked MRCS MCQs and can be installed alongside the 'negatively marked' versions of the program already developed for the anaesthesia and medicine postgraduate examinations.
