Good luck the OP, the best advice I can give you - read through the question/your answer three times before proceeding to the next. Any questions you are unsure on - work out by a process of elimination.
I did this exam a few weeks ago. I have worked in various corporate tech support environments for the past six years, so was rather cynical as to whether this course could actually teach me anything. I was wrong - I learned quite a bit, and my knowledge of group policies, NTFS, EFS, RIS and various other XP related features was greatly enhanced.
Over a period of four weeks I watched some training videos, read the Sybex book, took some practice exams and then passed the real thing.
People may question the logic behind taking xp/server 2003 exams - the logic behind me doing them - very few companies have/are moving to vista. Once I have my MCSE, I'll only be a few upgrades exams away from being certified for the 2008 equivalent qual.
