May I suggest you also get Tom Kytes' "Effective Oracle by Design". It'll really help you understand what the numbers mean.

If a newbie should have one piece of advice it has to be "Read the concepts document and buy this book!". The 9i OCP program would do well consider evidence of reading Tom's book rather than some dozy requirement to sit a class!
