Hi jstarguilford,
Since you've posted this in another Forum on this site, I've pasted over my response from there:
Many Test Takers spend 3 months (or more) on their studies before they hit their 'peak' scores, so it's likely that you just have not put in enough time and effort yet.
I have a few questions about how you took these CATs:
1) Did you take the ENTIRE CAT (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?
It's wroth noting that taking 6 CATs over the course of 2-3 weeks was NOT a good idea. Completing a FULL CAT requires a significant amount of energy and effort; it then takes time to properly review, practice and 'recoup' before taking another one. By taking so many in such a short period of time before your GMAT, you likely 'burned out' a bit - and that ended up hurting your performance on Test Day.
Thankfully, all of this can be fixed, but you're gong to have to make some adjustments to your study routine.
1) What is your score goal?
2) When are you planning to apply to Business School?
GMAT assassins aren't born, they're made,
