Yes, I complete it before few months.
This test covers a lot of Oracle features and is tough in my opinion, there a questions that are related to syntax of the commands, or to very specifical situations.
If you plan to take it, please prepare for him with covering all areas of "Test Objectives", which are almost 50.
Then you can be sure that you have chance to pass.
On the time interval when the tests was free in brainbench.com (01-14 July 2004) I was preparing 3-4 days for this exam only.
Before taking it, I was read a lot of documentation for all covered features and some questions from real exams (which I was take few months ago). After all preparation, I was answer correctly to only 30 questions.
Sorry, but I don't have it.
I can post definitions of some questions which I remember, if you want.
But you can do 2-3 tests on brainbench and see what are the real questions. This is will be some help, but they are at least 500-1000 in count, so they will help you to see what are the real questions, but you cannot see all of them.
Do not forget, you must do not make at most 4 attempts, because when you make the test number five, in the results for this exam will be published that you are take this exam "at least 4 times".
So, when you buy access for taking of this exam, you will have the posibility to take it lot of times. The better choise is:
Make two attempts to see what are the real questions. After that, prepare very hard covering all test objectives. Then you will be prepared to make one or two real attempts.
If you do not care about the Brainbench message, you can make a lot attempts, it's your choice.
Hope this helps!
