Hi Bancroftx,
GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your initial CAT score - and Official Score - show that you essentially performed the same each time (about 500 +/- a few points). Thus, we can likely use the data from that CAT to better define what you should work on in the next couple of weeks.
"Review" is an exceptionally important part of the GMAT training process; your ability to define WHY you're getting questions wrong is essential to defining the areas that you need to work on (and the specific things that you need to 'fix'). While a full CAT Analyzer or Mistake Tracker would provide a lot more information, there are some basic questions that you should be able to answer (and the more EXACT you can be with your answers, the better):
After reviewing each section of this first CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
5) How many Verbal questions did you 'narrow down to 2 choices' but still get wrong?
With just 2 weeks of potential study time remaining, you won't have time to properly cover every subject that appears on the GMAT. However, we CAN focus on the 'big point' categories; honing certain skills should be enough to pick up all of the points that you're looking for (and potentially more).
GMAT assassins aren't born, they're made,
