The SE1 is a tough test even compared to the other PE exams. I passed last October's SE1 with a lot of points to spare. This is what I did:
1) Study everything. Your test will probably focus more heavily on a couple of topics, but you won't know which ones they will be. Many people put in over 200 hrs of studying.
2)Bring all the codes that are listed.
3)Get as many of Alan Williams books as you can afford.
4)For topics you don't feel comfortable with, make yourself a step by step cookbook on how to solve them. Luckily I did this with bridge problems and it really paid off.
5)Tab all your books. This means codes, and any texts that have good examples. Breyer's wood design, Amrhein's reinforced masonry etc.
6)Bring earplugs to the test with you, it can get loud in there with all the book pages turning and you don't have time to be distracted.
7) Work as many problems as you can. You aren't going to have time to figure out anything new during the test.
8) Be careful and read the problems twice. You will see what I mean after you work the practice test from NCEES.
good luck
