I'm sorry to hear this. However, I am so glad that you are not giving up. You now know what to expect - regarding the types of questions that are asked. And you are correct, they were mostly situational questions. I read chapter-by-chapter PMBOK, Rita, and PrepCast. Any answers on Rita and PrepCast quizzes that I got wrong, I went back through the material and online to research. When I had reached the end of the PMBOK, I started taking the simulators. I first used Lehmanns and scored a 62%. This is the most challenging of the simulator tests that I cam about. However, it gave me a different perspective and allowed me to further research the answers I got wrong. I highly recommend taking this test.
I then did many PrepCast simulator tests, everyday, and again studied what I did not get right. I took Lehmann's again 5 days before the exam and then focused on studying and studying the answers that I continued to get incorrectly.
You have to understand, that the PMP is not about testing your knowledge of PM procedures and definitions and tools. It's all about applying the knowledge you have to situational occurrences. You used the knowledge you have of the processes and definitions and tools and apply it to situations. even then, the PMP answer may not be the answer you would chose. above all, you have to think about what the best answer is for that specific situation.
Keep at it. and review other's lesson's learned to gauge which study plan will work best for you. We are all rooting for you.
Time yourself on your simulators and practice process of elimination, because many of the exam questions will come down to this method in finding the best answer.
good luck!
