This is one of those exams that you have to know what you are doing. I learnt the subject so i finished in 30 mins and got 100% another chap was convinced he was going to fail and so he resorted to learning questions and answers parrot fashion and he scored 98%.
All the questions on my paper last November were straight from the question bank, even the values were the same.
My advice, learn it ( the subject and the database), pass it and forget it. It's been a year since i finished my exams and i can't remember a thing!
Good luck.
