understanding of the new pattern of this examination from the year 2000 It is the first book of its kind wherein the author has tried his best to make it easily readable and easy to follow It incorporates about 3500 extended matching questions (EMQs) covering all the major topics More stress has been laid on the topics which are rendered important from the point of view of the PLAB examination First timers (beginner aspirants) as well as those who have been preparing already will find the Handbook equally useful The author is quite hopeful that the latter will find it of immense use for revision and refresh whatever they have read before The author got the idea of writing the book when he along with his friends and colleagues was preparing for the PLAB examination This new pattern examination was totally new so the author and his friends had to face a new unknown challenge hence they felt the need of such a book all the more This book has been written with the first hand experience gained by the author himself Learning can be self or from the experience of others The author was not lucky enough to learn from the experience of others so he had to venture himself in the blind alleys However, the experience had been quite useful and hence this book The author is quite hopeful that it will meet the needs of the students in their preparation of the PLAB Candid

first wrote the book, being the first one in the field, just after first exam based on new pattern, I realize it had questions, which were difficult and not really suitable for PLAB Over time, we have learnt more about GMC questioning style and topics of interest and importance We have tried our best to add on the relevant questions and change the previous ones to make this book an essential read for all PLAB aspirants First time (beginner aspirants) as well as those who have been prepairing already will find the handbook equally useful We are quite hopeful that the latter will find it of
