KillerGMATHere are my two cents:
a. GMAC maintains standardized test conditions for each and every student who gives the test,
meaning any of student who faced any abnormal circumstances like power outage does in fact
hinder ability of his / her performance. The experience that you received at test center seems to
be counted as one of these and surely should be reported back to GMAC. I am hopeful (most likely)
you will get a free reattempt and boost up your verbal score this time.
b. Get an ESR to know what actually happened. In this way you doubts will be realistic and assist in taking
you more rational decision.
The B schools always look at your BEST score, so hopefully you shall be good to go even for you reattempt.
