Hi Paul,
My prep time was 3 months -
First 2 months - 4-5 hours a day, later 10 hours a day.
I started with Headfirst (forgot to mention above. But i feel this was not needed, Rita and PMBOK is sufficient). Then Rita, cover to cover twice. Then PMBOK, ( I read once, then skimmed again). [Rest, as mentioned above, I created sheets].
I highly recommend 1+ months of mock and 1 or 2 PMStudy paid mocks for for judging your score, (Prepcast is good for practicing).
MOST IMP - Take a day after each mock to check ALL your answers. 50% learning comes from mocks, whatever you study will never be enough because books don't contain situational scenarios and exam is ONLY situational.
I recommend you think of examples when you will study "Similar tools", when to use affinity diagrams versus mind mapping, focus groups vs facilitated workshops, when to use CPIF versus CP with award .. When to use Smoothing over Collaborating. They don't give direct hints or terms.
Stakeholder Analysis - think of real examples which stakeholders you will closely manage, and which ones you will keep satisfied. Rita has such in-chapter exercises (not end of chapter) which I liked.
