I have been self studying for 6 months now, have completed all the NT4 core, and found it strange the stuff they test on. Half of hte test will look like they think were all vegitables, then wham, they shoot you down with something that only got an obscure reference in the MOC, and the studie guides never even mentiond. For the most par if you score 800's on the practice test, you will pass the real thing. As far as studie effort. I can't keep my mind on the task at hand. On average i puta bout 30-40 hours in on one exam to studie, and prepare. More if i bomb it the first time. If you ahve any kind of experience, all you need is the cram, and a few practice test and our on your way. Workstation for instance was a joke, mostly navigation, and basic configuration/installation stuff.
