First, my condolences to all of you who didn't make it this time. I failed my first try both the FE & PE. I've been where you are and hopefully can offer some encouragement. Take some time off and enjoy the holidays with your family and start back fresh with the New Year. Your family needs some time with you before you go back to the grind.
Don't worry too much about the cut score as it's irrelevant in the grand scheme of things. Focus on your weakest areas from your diagnostic report and you will benefit greatly. If you took a prep class consider retaking it (if they offer a free repeat) or try a different prep class. Some people on this board have highly recommended EET if you are looking for a new or good review class. They offer a PM specific review that might help put you over the hump. The first time I took the PE I took the School of PE's review class and didn't pass. That was my fault because all I studied was the notes and problems from my prep class. In order to do well on this exam you need to work a lot of problems. You must be very comfortable with the basic concepts of each topic. Even though the concepts you study might be "basic" that doesn't mean it's necessarily easy. It's important to work as many problems as you can to cover as much of those concepts as you can.
There is no magic list of problems, pages from the CERM, or handful of equations that's going to guarantee that you pass. After finding out that I failed I made an outline of what I was going to do to pass the next time. I signed up for my free repeat with the School of PE and that helped. The next thing I did was I went on Amazon.com and looked up the CERM. If you follow the reviewers of the CERM you will see what else they purchased. It was through this method that I was able to find several very beneficial study guides that helped me pass. After finding about a half dozen or so study guides, my NCEES sample exams, the Goswami All-In-One practice exams, and my School of PE notebooks I was adequately prepared the second attempt.
Out of curiosity did any of you find the CERM helpful or was it useless on the exam? I found it worthless both times I took the PE exam. The Goswami All-In-One Exam Guide was a big asset and made up for the CERM's deficiencies. Hang in there and don't give up.
