Limped in with 730 - did well in all areas apart from "Designing Client Configurations" where I only got 50% questions right so the score took a big hit there.
55 questions, 2 hours, 700 passing score.
I used the sybex (70-685 & 70-686) book and the measure up tests, in hindsight I think I'd recommed the official MS book which just concentrates on the 70-686 stuff over the sybex book though.
The measure up test questions were good and quite tough, probably harder than the exam questions, I found this with the 70-680 too.
Good luck to anyone else studying for this one...
