Took this one today and scored a very satisfying 962.
Was rather nervous beforehand as it was the first time I’d taken an upgrade exam. Didn’t know what to really expect apart from knowing this exam is a combination of TS:70-680 and PRO:70-685. (I also found a few threads on this forum of other people’s experience just to give me an idea of what to expect).
So anyway, I found the first set of questions (which I’d imagine was the 680 section) to be very straight forward. When I then hit the next section, the exam difficulty in my opinion stepped up several notches and at one point I did start to worry a bit. Luckily, my previous experience with the 2003 MCSE and the Vista EST MCITP helped massively with understanding the finer details on some of the questions. Had a few too much marked for review at the end & was starting to run out of time, so was expecting something around the 700/800 mark but then found I scored a lot higher than my initial expectations much to my delight

So all in all, a good day!
