Hi Rose - Oh my goodness, this is not a very timely reply. Perhaps you have now passed. (I hope so) My most sincere apologies for not replying sooner. This is not an easy exam and try not to be so hard on yourself. Rita Fast Track is okay for the tough questions, but I think they were more off the 3rd time I took it. I found the PM Prep Cast Exams very helpful. And all the monitors and group of folks who respond are wonderful. Wrong questions are very important; the right answer is important, but we learn from our mistakes....most of the time

Some people are better test takers than others. It doesn't matter. PMBOK changed and I have not studied the changes thoroughly. I would recommend using the PM Prep Cast and if you have already used all the tapes and extra materials, taken all the exams; I would go to aileenellis.com/ - I like the tone of her material and down to earth explanations. She seems to unlock the mysteries.
Once again, my apologies for not responding. It was about 8 months ago that I moved and in all the craziness I must have missed your posting. I will hope that this post finds you in the passing zone! If so, congrats. If not, do not fret, Remember, ""A rose by any other name would smell as sweet" - It is the content of your heart that counts. All the best.
