I guys - it's been over a year since getting my MSDST. I am now working on the MCTS and have the Press Book. I'm only on Chapter 4, but am getting 78% on the Certification mode (45 questions) on the practice software. How long do you think it takes to get aquantained with Vista? I don't use it in every day as I use XP at work and at home. The boss let me have a laptop with Vista Business on it, but now need Vista Ultimate in order to practice other things. Just wondering how long I should take before I go ahead and take the REAL test. Any info would be appreciated. Thanks.
