I passed after 2 attempts a year ago, a buddy of mine is taking this Oct. Test which reminded me about this site. I STALKED the hell out of engineerboards.com and it helped a lot so I figured I'd login one more time and give the best advice I could.
In the afternoon trans. Test, do the 'Other Topics' section First! There will be about 10 of them and both of my tests had them at the end grouped together. These problems are an easy 10 dealing with hydraulics, hydrology etc. Trust me, do them first. I made mistake on my first attempt and just got to these problems with 15 min. Left and it screwed me. You will find many problems taking longer than you thought. This worked for me and I think it would work for most people. After nailing 10 at the start you will also get a nice confidence booster. Also, all of this is assuming you put your time in doing a LOT of problems from the recommended sources beforehand. IMO you will have very little chance of passing unless you actually do tons of practice Problems. Good luck Future PE's!
