There is a company called actualtests.com that sells the exact questions and answers to just about every certification test for $100. I got a bunch of them off ebay for $10. The 9i new features one is legit. The questions were word for word off the exam. You can buy the tests individually now for $3 off ebay. What I think they do is buy the 'practice tests' and pull the questions out of there. The practice tests are probably the actual questions. It's my best guess. So if your spending $100 on self test software, next time spend $3 and get the real thing.
