Hi gmdsat,
At this point, the At-home/Online version of the GMAT has been around long enough that it's become a standard option for most (if not all) applications. That having been said, if you're that concerned that a particular School/Program would prefer that you submit a Score taken at a traditional Test Center (and not take the At-home GMAT), then you should contact the School directly to ask.
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) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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:
4) What is your overall goal score?
5) 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,
