Hi SeyedAliTayebi,
The most accurate CATs/mocks are the 6 from GMAC - but there are a variety of factors that can impact your score results on any individual Test. Based on these 3 results, you are likely a really strong overall critical-thinker (which is great!) but if you did anything during these CATs that doesn't properly match-up with how you will take the Official GMAT, then the results might be inflated. For example, if you saw any of the questions before you took these CATs or you changed the parameters of the Exam (such as pausing the Tests) - then the results might not be an accurate reflection of your actual 'ability 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:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? Have you used any other “brands” of CATs/mocks?
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)?
4) 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,
