Hi, I passed 70-270 today with a score of 952, which I'm really pleased with!
The Sybex book proved quite useful, it was a great aid and proved crucial when I actually sat down and went through the exam. The TechNotes from this site and CBTnuggets really helped too. I'm also a fulltime PC tech so I guess that gave me a bit of a head start, as well.
I finished the exam with 30 minutes left from the allotted 135 minutes, after reviewing 5 marked questions and one unanswered question.
This was my first Microsoft exam after recently passing a flurry of CompTIA exams, and there is indeed a big difference in the style of question with the Microsoft test. Every question was at least a paragraph long and needed to be read through at least twice!
Thanks to everyone on this forum who posted useful information for this cert
