Hi gmat0305,
Before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on how you've been studying and your goals:
1) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
2) What were your Quant and Verbal Scaled Scores when you took the Official GMAT (the 530)?
3) Going forward, how many hours do you think you can consistently study each week?
You might also choose to purchase the Enhanced Score Report. While the ESR doesn't provide a lot of information, there are usually a few data points that we can use to define what went wrong (and what you should work on to score higher). If you purchase the ESR, then I'll be happy to analyze it for you.
GMAT assassins aren't born, they're made,
Rich
