sorry to hear that. Some tips:
error logs - seems you know your weak areas in quant - now you need to figure out the prob with V
devote time to verbal - a 20/80 time split is good.
Use MGMAT books
and powerscore CR
if you havent done so.
if you never scored over 30 in V it is pretty much a given you wont get a 700+ test day since you need probably at least a 35V to have any chance really...
Keep up the spirit and study hard!
