I had a book by Ghilani and Wolf from undergrad that I dug out of storage from 6+ years ago. I found it very helpful and it's very comprehensive but you'd really have to be expect to put in several weeks to really go through and read it all but if you do then you'd probably be in a good spot. You can pick-up the 12th Edition for like <$20.
I also had Practice Exams by Mansour. It was pretty helpful and there were at least 5-10 problems on the exam that were VERY similar to what he has on there. Really the best way to study, at least for me, is to do practice problems and note what I don't know and write down concepts/eqs on a cheat-sheet.
I only gave myself about 4 days to study for the Surveying Exam (took it yesterday) and was kind of busy so I didn't put in a lot of time as I should have. I printed the FS NCEES Cheatsheet, and wrote some additional equations on it, and bound that which was helpful during the exam
That said, Surveying Exam was quite a bear. Did anyone else feel that way?
By comparison, I finished the Seismic exam with roughly 15 minutes to spare and go back over problems. Surveying Exam, I was rushing to the last minute and I had just guessed/skipped on probably 5 of them. I felt like the Surveying Exam should have been 3 hours or cut down on some of the insanely long pictorial questions. They just had waay too many long problems, and the annoying thing is, I KNEW I could have satisfactory solved most of them since it was mostly Trig and some basic calculus principles but there was just no time to spend the time solving all the angles/coordinates. It really doesn't seem to make sense to be testing on speeding through surveying calculations or knowing "short-cuts". We'll see I guess.
Also don't forget you can use a TI-89 calculator on these exams. If I was forced to use that awful dinky FXIII Casio thing I used for the PE exam I would have not even come close to finishing.
