I disagree w/ HgTX's claim that "...the rules are supposed to be the same nationally"
In PA, solved problems are specifically OK, any reference is. All just have to be bound (3-ring is OK), no loose pieces of paper.
I took all of my solved problems, although I didn't use them very much at all. By the time you take the test, you pretty much know what you know AND don't know what you don't. There is no time to study a solved problem someone else did and learn how to use the algorithms and concepts to solve the one on your exam. If it is a problem you did, then you already know how to do it!
wketchen: As far as your notes in the margins, now that is a good move. Those notes, formulae, tables of common (and not so common) constants are what you will use for over 80% of the exam. That is really what they are testing for anyway; the PE exam is not a test on whether you can regurgitate previous solutions, and the writers do a very good job of putting real-world twists in the problems so that examinees can't often do that. The exam will test whether you can combine book-level knowledge with what you have learned as an EIT. If you have a good base of both, you will pass. Good luck.
