MCDST starting on MCSE

Hey guys. Got a question. I have my 70-270 test scheduled for the end of
June. In the past month and a half I've passed both 70-271 & 70-271 with
scores over 900 on both.

I guess I'm just wondering how different the 270 test is from the 271. I'm
not looking for specifics or anything, but I'm getting a bit tired of
studying the XP stuff and just wondered how much time I really need to invest
in studying for 270 while I still have the 271 & 272 fresh in my mind.

If anyone that has taken this same route has any advice for me, it would be
greatly appreciated.

Thanks,

Steve
