How do you guys take in material for exams? I mean i'm starting the MCSA right now i'm looking at the installing XP exam had a quick flick through the microsoft press book and was shocked that's a hell of alot of material to take in lol
My questions are I suffer with Homer Simpson Syndrome i.e I learn something new it pushes old stuff outta my head

Secondly plowing through pages is all good but what information should I be taken in I mean there is no clear pointers say hey Ally this section is important and it will be on the exam right now I am just reading text nodding my head and going hmmmm there is a possibility that will be on the exam but is it really relevant?
What are some study tips I mean reading a book is all good but damm it's a bit tedious how can I get stuff to stay in my brain dammit lol
