Has anyone taken the new CCNA Wireless exam? I am just curious how much it differs from the old cert guide. I have to have this cert by review time end of next month/beginning of Dec. I just took the 640-722 and failed miserably. It was nothing like the material I studied in the CBT Nuggets series or the Official Cert Guide. If the new test actually covers that material, I would rather just register for it than attempt 640-722 again.
