Failed 70-640 today

Just failed the 70-640 today, ended up getting 624... Was harder than I had expected and was mainly based on CA and rodc. It has been the most difficult one I have had up to date, used Microsoft Press Book, transcender videos and measureup. Will tackle it again in a couple of weeks!
