I had to reschedule this exam several time due the birth of my daughter and then leave I took; therefore I was under prepared as I didn't study much during this time.
Having said all of this, my voucher is approacing expiration and I had to take the exam quickly. However, I did manage to pass (surprisingly) this exam today by going from what I had already learned.
I only used the MS Press book and the sources related to it; and this forum, of course.
Now on the the 647 and this voucher expires on 7-22-10 (I don't think I'll make it).
