Hi jrrs,
Most Programs do not publish a 'minimum' overall Score requirement to apply - but they typically do publish average GMAT/GRE Scores and/or "middle 80 percentile" data, meaning that you can reasonably define the type of Score that you would need to be considered a good Applicant. You also have to be careful about trying to compare your overall profile to those of just a couple of other people (re: other Applicants who were accepted), since you will almost certainly differ from those people in certain key ways (and trying to 'mirror' someone else's details will not guarantee you anything). Your focus should be on properly 'marketing yourself' (re: all of the aspects that make YOU a perfect Applicant for that Program).
From your post, it's not clear where you are in the overall process, so it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) Have you put in any study time for the GMAT or GRE yet? How long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your goal score?
5) When are you planning to apply to School?
6) Are you considering any other Schools besides CBS?
GMAT assassins aren't born, they're made,
