I found this quite OK for the upgrade preparation. I passes the test first time. The coverage was OK but ORACLE seems to have updated the test content since the book went into print. There were some errors in the book (for example chapter about logminer has lots of errors about the V$ views and the procedure calls) but the general content seemed OK to me. Together with the test questions from Selftest Software and the ORACLE documentation this book should be sufficient to pass the test which is what this book is all about.
