Contains questions that are almost exactly like the questions on the plab -- difficulty level, subject material and question phrasing are all on the mark. Has the most in-depth, exhaustively comprehensive answers to EMQs available in any book on the Plab. It is also the only Plab book that bothers to explain **what the questions mean** ie what the examiners are getting at when they ask a particular question. This allowed me to improve my test taking ability as well as my knowlege of the subject matter being tested. The previous reviewer mentioned that only lettered answers are given for the best of 5 questions in this book. This is true, but to be honest for that part of the book its all you really need. Once you start to use this book you will understand what I mean. The January 2005 edition of this book is the best teaching tool for Plab Part 1, bar none. You should ideally start using it three weeks before the exam, but it did me an amazing amount of good even with less than two weeks to go (anything less than 6 days is not enough time, unless you are studying 13-14 hours/day -- not pleasant, but we all do that to ourselves sometimes, don't we?). Happy studying, I wish you the best of luck on your exam. (ireland)
