I, like bigmig, have also made a hobby out of taking these exams. I said I passed the PE Civil-Structural the first try but I left out the fact that I also failed the SE 1 a couple times before that! Thankfully, the 16 hr SE seemed much more practical and it only took me two tries on that one. But by then, I had probably seen every topic that could be covered and have quite a collection of the NCEES test pencils to show for it. He is right though...there is no consistency between tests and you may be close to passing once and come back and have all brand new topics to deal with!
Anyway...
YES, you definately need to take the codes in. Sorry, it sucks but you'll need them. They say the test isn't a "code" test but in my experience it relies pretty heavily on them. For the civil-structural test, if I was going to tell you there were any that weren't as important, they would probably be the lightgage steel and AISC 341. In both cases, you may have a question related to these but it would probably only be 1-2 total in the test. In my mind though, I wasn't going to let 1-2 questions stand in my way of passing...especially given that at least twice I was within 1 question of passing the SE1!
Not sure about PDF or online copies. Most of the groups that publish these are pretty closed to the secondary market and you won't even find many of them on amazon or similar websites. Your best bet is to try and work out a deal with your company. Maybe they will buy some and you will have to buy others. I probably invested between 500-1000 in extra materials and code books by the time I was done. Just part of the game. What really sucks is when they update the editions on you between tests and you have to reinvest the time bookmarking the new version from scratch!
Bigmig was right again when he mentioned about the reference manual. Remember, NCEES has access to these books too and they aren't going to layout every question just so you can turn to the right page. There is nothing wrong with using the SERM and CERM but you need to make sure you understand the concepts and really with the material codes you need to just sit down and go through them making notes and references for yourself. Once again...it's all about putting that time into it.
I would only use the NCEES problem book to get your timing down and get used to the way questions get asked. I was told once by a professor who had helped write the new test that the NCEES book is mostly comprised of questions that were either 1) statistically thrown out because everyone got them right or 2) were written in such a way that different codes/references/methods could contradict them. I would not equate confidence in that test with confidence in the real one.
