GMAT score 630(Verbal very poor)

[rags]

Folks,

I took my GMAT today and I should say the sky had fallen on my head. I managed just 630(Quant : 48, Verbal : 27), I was aiming for 700 and now have to retake the exam. Any advice on

1/ How many weeks I should study further (before I loose steam)
2/ HOW WILL I IMPROVE MY VERBAL SCORE!!!!

Here is what I have done so far

1/ GMAT PREP 1 (5 weeks back) - 620 (Q-46, V-31)
2/ GMAT PREP 2 (Next day) - 610
3/ Kaplan CD 1 (3 weeks back) - 540 (Q-31, V-27)
4/ Kaplan CD 2 - 560 (Q-39, V-28)
5/ Kaplan CD 3 - 620 (Q-37, V-37)
6/ Kaplan CD 4 - 580 (Q-41, V-29)
7/ MGMAT Free Test - 650 (Q-45, V-34)
8/ MGMAT 1 - 670 (Q-45, V-36)
9/ MGMAT 1 - 660 (Q-45, V-35)
10/ MGMAT 1 - 680 (Q-47, V-35)
11/ GMAT PREP 2 (reset) - 710 (Q-49, V-38)
12/ Princeton Free Test - 600 (Q-50, V-20), tired and not concentrate much

As you see I am not lazy and did my work but consistently got low verbal score. I read Manhatten sentence correction, critical reasoning and all OG guides(both 10th & 11th edition). Don't know where to go from here

Dear friend,

I think improving the verbal score is through a modern way of learning vocabulary and some people struggle with time to finish the verbal section. You can find all the information on this link:

Hi rags

My scores are more or less similar to yours in practice tests
How did u feel the real GMAT d
Did u run short of time!

I did not run short of time on the Quant. I paced well, sometimes guessing tough questions. One verbal I had to hurry on last 2-3 questions. Time was not the issue, I might not have paid much attention on verbal as I thought I did very well in Quant. I was not able to recognize patterns in many of the sentence correction questions, might have hurried little on RC. Not able to sleep previous day did not help either.
