And carefully read the questions, more carefully than you read each our forum purposes and post in the wrong one. Razz

With 047, you need to emphasize carefully reading the answers as well...

I remember some where the answers were extremely similar and more than one was a 'correct' answer (where 'correct' is defined as a query that would return valid data). However one answer was a hair better than the others based on specifically what was requested.

You should be confident in all of the listed topics, but beyond that the exam is a test of time management. You will probably start too slowly by reading and re-reading questions and spending too much time on questions to which you do not know the answer. Set yourself a target for half-time (1 hour). I suggest half way though is a good goal (35 questions). If you don't meet that target then you need a new strategy, because the last thing you want is to leave questions unread - they might have been easy ones.

If you are in timing trouble (eg. Q30 after 1 hour), I suggest the following strategy.
- If a question seems fairly straightforward, it probably is. Answer it and move on immediately.
- If a question is VERY long, read the first line and the 5-6 responses, provide an educated guess without reading the entire question and move on. This will be hard to do, but you are already in time trouble and reading and understanding this question in full may cost you three questions at the end.
- If you get a tricky one (select ALL correct responses) on a subject that you are not expert in, guess it, tag it, and move on. If you get time then come back, but don't waste time on a question you will probably get wrong anyway.

Having said that that, there is enough time allocated to carefully read every question and response and to provide your answer(s) with a very small amount of time for thinking. If you have been staring at a question for 30 seconds or are re-reading it for the third time then it is time to move on. You don't need to get EVERY question right, so be prepared walk on by questions that are too hard.

Thanks you all!!! I passed the exam and scored 80%. The main difficulty was multiple answer questions, when asked choose all that apply or choose three!!
