I watched the Train Signal videos and am pretty decent at subnetting, I think. Going to look at some practice tests and go through the Cisco Press book. I've been slacking on my studies because I didn't have a date set, so I figured now that I did, it's time to light a fire and get it finished.
If anyone wants to throw me some random questions (not asking for exact questions that are on the exam), feel free. There's never enough practice.
