Yes, that's exactly what I am suggesting. Just do the exams and quizzes multiple times (I actually damaged the nerves on my right shoulder because I took way too many exams

). You need to pick up
a strategy, speed and comprehension, as I mentioned previously. After doing a few exams, for example, when you see that 'xxx is planning stakeholders engagements', you automatically know that at this stage
we don't have a change request in place because a 'plan' must be finalized before you can even use the change request for it. In picking up this knowledge, you eliminate those answers which talk about
sending a request. Or you discern between 'business documents' vs. 'project documents'. these are very important areas that the exam simulator keeps re-iterating and drills them into your head. Do not spend time
on PMBOK, PrepCast has done a phenomenal job in bringing PMBOK to you, by detailing every single question in great extent.
You can do it, and I'll be very happy when I hear that you passed it the first time. Make sure to let us know.
