This CISA study guide gets good reviews on Amazon by people who have passed the exam. If the goal of the reader is to pass the CISA exam,it seems to do a decent job in serving its purpose.
However, after reading the book a number of times, I find it mostly shallow and that it does not provide much information on how to actually perform an IS audit.
If the book is any reflection of the exam, it should be a breeze to pass for anyone who has a background in information systems management.
In all fairness: I have not looked at the CD or at the test questions and I do not have any other CISA material to compare this book with.
One positive point: including the book as a PDF file on the CD is excellent service!
