Hey Derek, sounds great. Generally what I tell students while coaching them is be less concerned about the inputs and the outputs as far as memorization goes. They will come in time as you are studying. Plus there are shortcuts to remember such as, "work data input = work information output" or, "monitoring and controlling = change request output EVERY TIME". You want to know the differences between the different tools and techniques within the knowledge area. There are pretty quick ways of doing that which we discuss in our coaching. But ITTO's are good to know.
Also remember that there are the big four sections that PMI will test on: Quality, Cost, Risk, Procurement. So if you are uncomfortable with those, think about getting some help because those are knowledge areas that you need to know. It has seemed that the PMP exam will be heavy handed with at least one of those four knowledge areas when creating your exam.
You mentioned taking exams, fantastic idea. You need to get your testing endurance up for the exam. Most people struggle with the fact that you are taking at 4 hour long exam. With that said, use the exams as a report while you are getting your testing endurance up. Example: you take an exam you see the lowest score for knowledge areas is in risk. Go back, read PMBOK Risk chapter make up new flash cards, study the ones you have, take some quizzes on risk to raise your score, then take another 200 question exam. I would do a Plan-Do-Check-Act with it.
Lastly just know speed is the key, but efficiency and well calculated study methods are as well. People generally don't get the results that want on the exam not because they didn't study - rather they didn't study the right material at the correct depth.
Good studying,
Derek
