Hi nehjha02,
Your score is at the low-end of the 'range' that the Schools that you listed would find acceptable, so you can certainly apply with that score. I imagine that most Admissions Experts would recommend that you retest, but you should ask them anyway.
In regards to the 2 CAT scores that you listed:
1) When did you take those two CATS?
2) Did you take the ENTIRE CAT each time (including the Essay and IR sections)?
3) Did you take them at home?
4) Did you take them at the same time of day as your Official GMAT?
5) 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.)?
6) Did you ever take a CAT more than once? Had you seen any of the questions BEFORE?
You could potentially pick up some points and retest in January, but you would have to be really efficient about your studies (and you'd have to learn/practice some new Tactics).
GMAT assassins aren't born, they're made,
