Passed 70-685. Scored 978 in 75 minutes. Used MS Press book, CBT Nuggets and got Darril's book for a few evenings. Some scenario questions were twisted and some you could answer even without reading the scenario at all. Got some questions, which were in 70-680 Overall opinion - if not scenario questions, this exam could be easier then 70-680, but you have to be familiar with Active Directory and know by heart Windows 7 GPO.
