Hi noelis99,
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, but the CATs from Kaplan and
MGMAT 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). In addition, there are a variety of other factors that can impact your performance on a CAT/mock, including how well-rested you were when you took the CAT, the time of day that you took it, the section-order, the testing environment, etc. At this point, there's no practical way to determine which of these 3 CAT results is the 'most accurate' assessment of your current ability-level - and you should NOT take another CAT too soon (as we don't need any of that additional data at this point - you likely have the knowledge to score in the mid-600s right now, so your time would be spent at this point learning and practicing the necessary Quant and Verbal Tactics to score at a higher level).
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? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what dates (or approximate dates) did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
