640 Q-43, V-34... HELP needed.

[gmatter7]

Hi,
I gave GMAT today morning, I got 640 Q-43, V-34.
I am utterly shattered with my Quant score.
My MGMAT scores were - 620,620,640,640,660,690(last week i gave the last 3)
43 is the lowest Quant score in any test.
While giving the exam,i was doing great in Quant, never felt like i wd get such a low in Quant. I got a bold face CR in Verbal, verbal was decent enuf.
This was my second attempt, i had given it 2 yrs back - 510 Q-47,V-15.
I have done hell lot LSAT stuff for RC and CR, which helped me a lot.
I need some advise to better my Quant now.
Regards
