I have read the MS Press Upgrade Book (292/296), ExamCram2 and playing in a lab off and on for 4 months. I also have the netfresco document to help

. I am starting to re-read both books again. I also have 3 years experience with Server 2003 at a medium skill level. I feel I cannot absorb another bit of information. I guess I am ready to take the test.
How did you know when you were ready to take the tests with soooooooooo much information?
Are there other resources I should be using other than TechNet?
I am planning to write 296 a week later after 292 (if and when I pass).
Thanks!
