Help in improving GMAT score

[MCapri]

Hi All,
Just joined the forum today,but reading the posts from a couple of weeks. I started my GMAT preparation around 5 months ago and my scores are:

1. 450
2. 485
3. 580
4. 630
All these are scores from the Official PowerPrep Practice tests. I have my GMAT 10 days from now and aiming to cross the 700 mark. Need more of a help in Verbal.
The preparation books I have are:
1. OG 11
2. Kaplan Premier
3. Cracking the GMAT:Princeton
I am from India and not able to get any books from Manhattan. If anyone could send me the links of Manhattan Verbal or anything which will help me to improve my score would be great.
