Hi desertwarrior,
If you took these practice CATs in a realistic and test-like fashion, then you appear to be in position to score at a high level on the Official GMAT. As such, I have to ask when you plan to take the Official GMAT? I'd also like to know a bit more about how you've taken these CATs:
1) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
2) Did you take them at home?
3) Did you take them at the same time of day as your Official GMAT?
4) Did you ever do ANYTHING during your CATs that you couldn't do on Test Day (pause the CAT, skip sections, take longer breaks, etc.)?
5) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE?
GMAT assassins aren't born, they're made,
