Dizzee,
This is what worked for me (Transpo PM April '07)... it won't work for everyone, but it is an option and what I did to prepare.
You may want to start outlining a notebook for each discipline. In each, list out the topics you will see in each section (including both breadth and depth topics).
Take notes and read up on each topic. Gather references. Make a schedule of what you will cover when. Don't be afraid to tweek your notes as you go along. Use the CERM, old college texts, online Military manuals, etc.... Download and print the MUTCD, HCM.... get all of the suggested books (beg, plead, borrow, copy, get work to buy them... whatever it takes)
After you have created your initial notes, start going through 6 minute solutions... after you go through them, do a post-mortem... add notes and equations on approaches to problems... tab the references as you are using them. Work sample problems, there are many here on this board as well as in the companion book to the CERM.
Take the NCEES practice exam, take the CERM practice exam (much harder than the real deal so don't worry if you don't feel you did well)... again, do a post-mortem and add to your notes.
The test is not all plug and chug, there are a lot of content questions (40/60, 50/50, I have heard many splits).
I felt by approaching the test in a scheduled, logical manner, I was able to control my notebooks and what I had where.
I copied a lot of tables from the CERM and various texts for my binders to avoid unnecessary flipping during the exam.
I would also suggest a unit conversion book to again save time (for any discipline).
Hope this helps you do develop your strategy for passing this test!
Good luck!
