ANCC Board Certification

I am taking the ANCC Generalist Board Certification Exam for Med/Surg RN's on October 3...has anybody out there done this already? Do you have any suggestions, tips, survival techniques??? I've worked on challenging med/surg floors since graduation (91), but haven't taken any 'real' tests since the boards! AAUGH!! Test anxiety is setting in again...maybe a good brownie recipe...Thanks!
