Query: No good for the exam

This book is more of a guide to consulating than a coursebook. Very little of the contents are applicable to the exam - look at the braindump sites and then compare the information presented in the book with that asked in the exam - there is NO correlation. If you want a VERY high level VERY general guide to design, this is the book for you. If you want any chance of passing the exam, forget this book, look elsewhere. The relevant material (no more than 10% of the total contents), is discussed in SO little detail as to be pretty much, (but not completly) useless. If you have done a course or used other material to revise from, this may add some value, but otherwise it is not going to get you through the exams. First Osborne book I've bought, think it may well be the last.
