I am very interested in taking the 70-500 exam:
http://www.microsoft.com/learning/exams/70-500.mspx
I have been supporting our WM5 environment since it came out pretty much and
I feel I have a good understanding of it but some of the skills are outside
of my knowledge. I have yet to see anything about a book to study for this
exam, only a course. The skills that I'm most worried about aren't fully
covered by the course anyway so I'm not sure how to study for this to make
sure I could pass it.
