count me as another that has the cert. got it not quite in the same timeframe you are looking, maybe 2 years ago now.
my suggestion- go to the library and check out as many up to date materials as you can.
they're on a new pmbok version since when i took it but there's a useful page in there with the block diagram of "steps" to each phase of project management. memorize that to short term memory and write it down before you take the test. it's good for easily answering a few questions. do the same with the formulas.
remember that the test is not about real life project management but about the theory out of the pmbok.
what i found as a technology portfolio pm was that it was alot of busy work. maintaining/updating project documentation was expected but the babysitting was present also. each technical resource i would work with would have a predefined zone of things they do. anything that fell outside of the zone and lay in between two zones required babysitting to bring people together and get them to decide on who was going to "own" the problem. I existed in a weak matrix slanted towards the functional side. as such project resources also were operational resources and the inherent conflict of interest made it an interesting environment
i wouldnt stress too much on the test. raed the materials, take a boatload of sample exams. rita m's book was considered an harder test than the pmp at the time so i prepped the most with that. stick to the standard test taking techniques. rule out the stupid answers (2 typically) and if you have to guess, you increase your chances. be aware when you take the test, sometimes an answer to a question will be embedded in problem statement of another question. figure if you know 50% of answers outright, and rule out half of the answers for the ones you guess on, statistically, you'll be around 75% which will pass the test.
be wary that a PMP itself may not get you a job. you might have to go the consulting route first to build experience in PM even with management/technical experience.
if you have to go back to class for the education portion, you'll more than likely get a free copy of the pmbok. if not physical, then digital. you might even be able to download it from pmi.org once you register to the organization and pay dues.
