Taking the Certifications Test

I have been studying for the Windows 2000 professional test for about a year now. I am currently working in a MIS department and have been here for the last 2 years. I have seen many books(Sybex, Windows 2000 training kit + resource kit). I have also purchased the Transcenders as well as the Troy test CD. I am not sure if I am intimidated or if I even know enough to take the test. I just need some heads up on a true study strategy as oppose to jumping around on. What I mean is, what am I to expect, what should I really key in on, and what is the best study strategy?
