Need Help, got meagre 640 ( Q 48 V 30)

[nitin360]

hello,
i took my GMAT on 31 aug 2009,and got 640(Q 48 V 30). i m from India,
before actual exam
my mock details are as follows.

first diagnostic Crack GMAT 620 ( in jan 2009 )
kaplan test 1 640
kaplan test 2 660
kaplan test 3 670
kaplan test 4 670

i took only GMAT Prep 1 ( 720), because i had done OG before taking GmatPrep, to remove any changes of inflated marks i did not take GMAT prep 2.
in mock tests i used to score 35-40 in verbal, but in actual exam i was not able to concentrate in few starting question. i did some very silly mistakes in starting SC question. But once u say CONFIRM u cant change it

i really need to improve my score, because i want to do MBA (with scholarship)..
please help me .. what should i do now..
