I took the Civil PE (Geotech PM) exam April 2008 in Reno Nevada. It was my first time taking the exam and I passed. However, coming into and out of the exam there were several things that I would have done very differently.
First, I recommend you take a moment to place your individual scenario into one of the following categories:
1) You are a fresh-faced college grad taking the exam early.
2) You are an engineer of some experience who has worked in a number of disciplines without having specialized in any one.
3) You are an engineer of some experience who has specialized in a discipline that is covered by an exam depth module.
If you are category 3 then I estimate that you will make short work of this test (I will elaborate more on this later). If you are 1 or 2 then, my friend, you have your work cut out for you. For the record, I was a 2 when I prepared for and took the PE.
Regarding the AM vs. PM, Mr. Lindeburg's CERM led me to believe that the bulk of my preparation should be spent covering a breadth of topics. This is wrong. The AM portion is fluff, a fact everyone seemed to know except for me. Most people finish the breadth section with over an hour left on the clock. I feel that I could have spent only a week and a half or so on each major breadth discipline and still scored a perfect on the AM section.
For AM preparation, I recommend first printing out the NCEES list of Topics Covered for the Breadth portion, then immediately go into solving the 6 minute solutions problems for each topic. Don't worry too much about theory or all the different little hints/tricks in the depth portion of the 6 Min Solutions. The breadth problems on the exam will be mostly straight-forward with only a few curve-balls that you will probably be able to spot. If you understand how to solve each type of problem on the NCEES list you have successfully prepared yourself for AM
The PM is what you need to study for. The PM is MURDER and will be the hurdle that shatters your self-confidence until the exam results arrive months later. My recommendation for you 3s is to hold fast to your specialized discipline. Print out the list of NCEES topics covered for your specialized discipline and delve delve delve into them. Theory, problems, 6 minute solutions, lengthy essay type problems anything you can find. You will not regret OVER-PREPARING for the depth module!!!
The same goes double for you 1s and 2s. I recommend that you run through your breadth studying first then take some time to ponder your options for depth. Some depth modules require lots of reference manuals, do you have access to those? If not, you may want to consider Water or Geotech. Personally, I regret taking the geotech depth module, I think water would have been a better choice. The geotech topics are all very complex and your breadth preparation doesn't touch on most of them. Water depth topics are covered well by the breadth topics and then environmental gets added which is not so difficult.
No matter what you decide, collect references. If you are fortunate enough to have a university within driving distance, find out how to become a community borrower then ransack the engineering library for books covering depth topics. The CERM is all you really need for breadth, but you should have a book with a chapter or at least several pages covering each topic on the depth list. I rolled a suitcase into the exam with over a dozen books that I had checked out or purchased on line. Every single one of them got opened during the exam. Every single one of them yielded an important answer/clue.
Here's a list of the references I took in (remember, I took the Geotech depth module):
CERM 7th (Old and did not include much construction)
CERM Quick Ref 2nd
DAS Fund of Geotech 2nd
Len Webster Enviro/Civil Dictionary

A book that has not been opened prior to the exam is less useful than one you have been working out of. At the very least, scan the table of contents and index for the topics listed by NCEES then tab those chapters/pages. With the study method outlined above though, you should have time to actually read through and gain some understanding of the theory behind the topics.
One thing that I'm still not sure of is crib sheets. I created crib sheets for each of the breadth disciplines. It took a lot of time and I did not refer to them during the exam but perhaps the process of creating them helped me review and cement some of the concepts? Hard to say if doing this really helped. Tabbing the crud out of your CERM is not very helpful. The index is quite good and you will be relying on that, not your tabs. Something else that is helpful is noting the location of each topic on the NCEES topic list then highlighting it's line in the index.
One thing I am sure of is the NCEES practice exam. There were several exam problems in both the breadth and depth modules that were taken almost verbatim from the practice exam!
The bottom line: This is a board certification. This is you proving that you are a responsible, well-trained, professional engineer and someone who cares deeply about what you are doing. If you think you can approach this test with an attitude that this is just another test you have to pass then can forget about you are not ready for professional liscensure. My attitude towards this test and engineering changed radically during the process of preparing to take this exam. I hope you have a similarly transformative experience if you are not already there ...
