670 on GMAT Prep : Actual GMAT on Jul 22nd,2011...

[girigmat]

Hi,
I have been a regular visitor of beat the GMAT forums for the past 4 month and have really been helped by the various debriefs and the strategy articles that this site provides.
I have scheduled to take the GMAT on July 22nd,2011. I scored a 670 on my first GMAT Prep test..with 45 Q and 38 V ...there were quite a few careless errors in Q section and made errors mainly in SC and CR in the verbal section.
Am looking to score 700 + ..still undecided whether to go ahead with July 22nd,2011 or postpone this date to strengthen my weaknesses.
Any insights into whether it is possible to get a 700 + of dedicate practice for one more week or is it better to postpone to somewhere around August 1st week?
I guess today is the last day I can potentially postpone so wanted to get some insights before I take the decision.
Regards..

This is a decision that you need to take. If you feel confident that you have covered all the bases compared to last time then go for it. But if you know your obvious weak areas and you think you CAN improve them in a given time frame, then post-pone it.

thanks Prodizy..do you know what is the best material available for getting some quick improvement on Verbal? I have exhausted OG 12 and Manhattan SC Guide..and am looking for an improvement to 40/41 in verbal..
