Eric,
As a 42 year-old automation designer who decided to head back to college last year when the economy went sour, I can add a few helpful study hints:
#1 - Remember, it's not how much you study but how WELL you study. Read the sections that you feel you are struggling with and make a question sheet for yourself. Keep going over the tough questions until you can answer them correctly without looking back into the rulebook.
#2 Study right before going to bed. The mind has a way of re-churning the info during sleep and will help lock it in your mind.
#3 Dont try to cram all night unless you know from experience that you are good at this. Get a good nights sleep and study again when you wake up on the day of the test.
#4 When taking the test, read the COMPLETE question before answering.
#5 If you have time when you complete the test, go back over the questions, but by all means DO NOT change your original answer unless you are SURE that you made a mistake.
Here is a good pre-test site that I used before I took my test last year:

Be aware that the test was created for the 2002-2003 rules.
Good Luck,
