haha, nah im not saying against going through the database, its a fantastic tool, I would have done a hell of a lot worse without it! The thing I'm saying is that in my opinion, unless you get a very nice exam, some extra knowledge above known questions will be needed. Most unseen questions are along the lines of others as AVGUS stated, but there are some out there that are completely different. I had about 10 questions last week in one exam that were on completely different areas than are covered by most other questions, still all within the sylabus but things that other questions may not cover, and these would have accounted for nearly 20% of the marks for that exam. In all honesty, you are making good progress and I'm sure you would have no problem passing the exams, just I think extra work beyond databases (or a very nice exam)is needed to access the top marks.
Hope this doesn't cause any debate!
