Hi Vipul78,
While the At-home GMAT offers a certain amount of convenience, it also comes with certain 'issues.' The section order is 'fixed' (Quant and Verbal - in one sitting with NO break, then the IR section), so if you are going to take that version of the GMAT, then you have to train to perform at a high level for over 2 hours straight - the time it would take you to work through those first 2 sections). In addition, a number of GMATers have reported various technical issues with how their At-home Exams were administered. If you've been training to take the GMAT in the traditional format (at a Test Facility with two 8-minute breaks, etc.), then it might take you some time to properly adjust to the At-home format.
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?
3) On what 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 take the GMAT?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
