Hi,
I passed my exam last August.
Preparation is critical as well as a healthy positive attitude towards the whole process and experience.
How to do those two things is somewhat individual, so you do sort of have to find out what works for you.
I agree with the tips provided in this thread about reading and re-reading the PMBOK guide. Using the PM Prepcast and other books and resources were helpful to me as were taking practice exams.
I think taking the full exam helps - so you have an idea of how long you take over all, so you can get a breadth of questions.
Personally, I tried not to fixate too much on what my overall scores were on the practice exam.
Instead, I tried to focus on what might be missing in my understanding or test taking abilities.
Why did I not get that? Was it the way the question was phrased? Did I not understand the definition of a term used?
Do I need to re-read that section in the PMBOK Guide?
Basically, I wanted to make sure bit by bit, I was filling in the gaps for myself.
So it's not really about 'seeing the same question twice' But about being more confident if they asked a question about x. They can ask it in all sorts of ways and I'd have a good chance of getting it right.
Hope that helps.
