Summary: very helpful
Review: This product helped me passed the exams. It has 200 questions for each exam. I did the questions in the timed mode in the week before the real thing. The questions are a little bit harder than in the exams, which makes you feel comfortable during the real thing. And it helpes you to understand the concepts well and to realize what you are weak at. It also has some scenario questions, which is what Oracle is adding to its exams.
One thing about it is that the questions are not numbered. When you are doing the questios, especially in a timed mode, you may feel lost about how far you are from the end.
Overall, it is phenomenal. I recommend it to all who want to go to the exam confidently.

Summary: A Disappointment
Review: What a disappointment. I'd get my money back if I could. Lots of errors. Questions have little relationship to the Sybex study guides. This must be something Sybex bought from a third party. For instance, a question for the first exam mentions the CASE statement which is NOT mentioned in the Oracle 8i DBA SQL and PL/SQL Study Guide. I checked the errata section of the Sybex website for this product. It said no errors listed. Hah! What a joke.The test interface is terrible. Has a built in self-destruct key called "Score Test". Click it by mistake and you are hosed. The test stops and you can't get back to it no matter what you do. These practice tests are nothing like the practice tests in the Sybex study guides. I liked the tests in the study guides and was disappointed here.
