My two cents on the topic at hand....
This Oct was my first attempt at the PE exam. I took the Geotech PM session. I got the PPI books and the NCEES practice exam. I prepared diligently for the exam. I managed to fail the exam. What I observed was that the NCEES practice exam was easier than the PPI problems and exams, as well as the actual PE exam. I felt like the AM session was alright; there were certainly topics I am not well-versed in and I had to guess at several questions, but that is pretty standard. We can't all know everything. The PM session was not quite what I expected. Meaning, maybe only a quarter to a third of the exam was actual standard work out problems that I had practiced from PPI books/exams and the NCEES practice exam. There were a LOT of concept-type questions on the exam, especially in the PM session. The truth of the matter is, like many others here have stated, you either know the concept or you don't. Many I knew and answered correctly (admittedly, some I only knew from field work and others I didn't know because I had not done that particular thing before in the field), and also several I stared at with wide eyes trying to understand what in the hell they were asking or talking about for several minutes before guessing and moving on....lol There were a good handful of questions that really stretched the realm of possibility in the Geotech world (I had a few that were straight structural and one or two that belonged in water resources) but since Geotech (and this also applies to Construction) is so connected with other civil disciplines, its expected that we know these things. In the real world, we have to sort out all sorts of random crap from clients and agencies and anyone else providing us with information. We also have to take any problem and figure out a way to solve it. The PPI book even discusses how to learn to read between the lines in exam problems, since there are what they call "distractors" in some of the problems. It is our job to learn the material so well that we are not distracted very often. As frustrating as it is to fail when you feel prepared, it tells us that we need to learn more and increase our abilities to solve (exam) problems, differentiate between minor differences in answers, and read the problems carefully. There were certainly several tricky questions, but what may have seemed deceptive to one person might have been a simple problem for someone else. It is a matter of what you know, as well as what material is on the exam. A PE stamp is a big deal, and there most definitely needs to be exams like this (i.e. minimum knowledge criteria) to ensure the safety of the public and integrity of the profession. Feel free to agree or disagree, but that is my personal opinion. I do not have all the answers on how to improve studying methods to pass, but certainly practicing many, many problems cannot hurt. I feel your pain at the thought of spending the next four months studying again, but I plan to suck it up and hit the books hard no matter how unpleasant it may be. I sure do hope all of us who failed this Oct exam are able to pass in April! If not, try, try, try again. We will pass eventually!
