Passed 70-643 on Monday. Exam was relatively straight forward with some interesting questions and a good mix up of the subjects tested. Ran into very little Streaming Media server questions but I never really use that so that turned out okay. They now added a little questionaire in the start where they ask for your proficiency level in experiance with certain products.
Will be attempting 70-647 on Monday the 7th, currently in the process of preparing for that and reading up on several key issues. From all accounts online this will be a very hard exam to pass.
Ofcourse I also updated the side-bar to represent this achievement.
