Happy to help!
1) I took all 4 hour practice exams on the Exam Simulator (

. After I finished all 8, I took 2 timed quizzes of 100 questions. All of this 2 months before the real exam.
2) I first studied the answers I got wrong and went back to review those areas in my notes and the PMBOK. I then went back to the the answers I got right and were flagged to make sure I didn't just make a lucky guess.
3) My trigger may sound strange: I was starting to over think the right answers and get questions wrong in areas that I had previously had no issues with. Almost like analysis paralysis. I was studying my mind numb.
4) My personal opinion, PMBOK is very difficult to memorize and don't recommend that folks dine in expecting to be able to do that. I focused more on understanding the "why" and "how" of the PMBOK. Although, the most helpful diagram to memorize is the Project Management process Group and Knowledge Area Mapping. I still have it on my wall!
5) The strategy I had was trashed once the exam started. I honestly didn't expect the questions AND answers to be so long. Best strategy, if it's a long question, read the last sentence of it first, then start from the beginning of the question. And you just have to train yourself to be super focus, pick out key words that identify what Knowledge area and process group you're in.
Hope that's helpful,
