Writing GMAT in 10 days, need advice

[AG Pennypacker]

Hi,
I am starting law school in September and want to pursue an MBA as well. To get into the joint program at the school I am attending, I need a 600+.

Ive studied for 2 months, beginning with 2 of the Kaplan cd tests, scoring 540 and 550 respectively.

Since then, I have written several tests including (in order):

Kaplan diagnostic (paper test in book): 610
GMAC released paper test: 630
GMAC resleased paper test: 600
GMAC resleased paper test: 640
GMAC resleased paper test: 630
GMAC resleased paper test: 640
CAT from mba.com (#1): 660
CAT from mba.com (#2): 700

Yesterday i wrote another GMAC released paper test (#52) : 670
and today i took another crack at kaplan with cd test #3 and scored a disappointing 550 (same score i got 2 months ago, in the beginning).

What can I expect on the real thing. I understand its near impossible to predict, but any feedback would be appreciated. And how is it that my Kaplan score is identical to when i first wrote 2 months ago.

These are your true score. Ignore Kaplan scores.
