All I used were the STERM, practice exams/problems and the codes themselves. For my studying I first went through the STERM cover to cover, only as a tool for me to learn the codes I wasn't experienced in (I'm only experienced in steel and seismic). After that all I did were practice exams/problems, (PPI Practice Exam, PPI SE Solved Problems, PPI 6-minute problems, NCEES practice exam, SEAOC Vol. 1and Connor's Bridge). For each practice book I'd do all of the problems, and then review the solutions, spending extra time on ones I missed. Then all I brought into the exam were the codes themselves, STERM and Connor's bridge. No textbooks / code refence books. I only used the STERM and Connor's Bridge book less than 5 times. For me, I felt that too much time would be wasted in the exam if I were to use a reference/text book to direct me to the code, rather than just going straight to the code itself. I know I am the outlier here, because the other 5 test takers with me had piles and piles of reference books and such, both on their table and on the floor. It looked daunting to me to have so much material, first thinking about what would be the book to grab on every problem and then finding the book among the library that was brought. I just had my several code books fanned out, none stacked top so I could immediately grab the correct one.
