Hi Evo23,
Assuming that you took each of these CATs just once, then these results show that you have strong overall critical thinking skills in both the Quant and Verbal sections - which is great! As you have noted, many GMATers 'feel' a bit more pressure when they're taking the Official GMAT (and some of that pressure occurs because there are aspects to Test Day that many people do not properly factor-in when they're taking their practice CATs/mocks).
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) Have you taken the Official GMAT yet? If you did, then how did you score?
2) How long have you studied in total? How many hours do you typically study each week?
3) What study materials have you used so far?
4) Did you take any other CATs besides these four? On what 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:
5) What is your overall goal score?
6) When are you planning to take the GMAT?
7) 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,
