Hi ZMan40,
So far, there has been no indication that any Business Schools are dissatisfied in any way with the At-home GMAT. By extension, if you're planning to apply to Business School at some point during the next year, then it's reasonable to assume that an At-home GMAT Score would be fine to include as part of your overall application.
That having been said, many GMATers have reported technical issues when they attempted to take their At-home Exams and the 'format' of that version of the GMAT is "fixed" (Quant, then Verbal - with no break in-between, then an optional 5-minute break, then IR). Having to take Quant and Verbal in one sitting is challenging for many GMATers (especially if you've been taking your CATs with an 8-minute break between sections). If you want to take the At-home GMAT, then you will have to be really rigorous about how you take your CATs going forward (and take them in the exact same fashion in which you will have to take the At-home GMAT).
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:
1) On what dates did you take EACH of your CATs/mocks so far and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
2) What is your overall goal score?
3) 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,
