I just passed my exam last week first time. I used this book, as I found the 11g OCP book so daunting, and I had already attended the 11g New Features Course a few months back. I was pretty much so convinced I was going to fail that I didn't even start revising. I'd have spent may be 8 times as long revising if I'd learned all my notes from the course, and been disappointed when most of it wasn't required and I believe I would have failed. My complete revision was based on this book, plus Kaplan self test for 1Z0-050. The Kaplan self test made it obvious that a couple of bits are missed out in the book (eg calibrate io), so I followed up on those with 11g Documentation from Oracle. But that said I cannot praise this book enough as it's possible to read the whole book several times before the exam and it's beautifully concise.
