Hi I'm an unqualified support technician with 18 months experience in IT support. I want to acheive MCP (and then MCSA) and intend to sit 70-210 Win2k Pro. The passing score of 700/1000, exactly how many questions can you afford to get wrong? Does this scoring method equal a straight 70% passmark, i.e get 40 of the 50 questions correct then you pass? Also, is there any kind of catagory pass system in the exam, i.e do I have to pass each individual topic within the exam, or is it just an overall grade? Thanks Phil.
