Hi adizephyr,
The scoring algorithm on the Official GMAT is far more complicated than most people realize. Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT scores can vary a bit based on the 'biases' involved in their respective designs. The most realistic CATs available are the 6 from GMAC (the 2 free CATs, and each of the 2 that come with Exam Pack 1 and Exam Pack 2), but the CATs from Kaplan,
MGMAT and Veritas are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion).
Since you are concerned about the accuracy of this recent result, then we should start with some of the more common, potential issues: had you seen any of the questions BEFORE (for example, on a prior CAT or in the forums here)? Did you do anything unrealistic when you took the CAT, such as pause the Exam, use a calculator, etc.?
Before I can offer you any additional advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied in total? How many hours do you typically study each week?
2) What study materials have you used so far?
3) Are these the only 2 CATs/mocks that you've taken? If there were others, then how did you score on those CATs?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
