I haven't taken any recent exams. For many months I thought about the MCDST \ncert, but then Vista came out. I could do the 70-271 and 70-272 then do the \nupgrade 70-621 test to Vista. What do you think? I'm sure I could pass both \nthe 70-271 and 70-272 in one month as I actually have been studying on that \nalready. Or, should I just do the Vista Cert instead?
