Hi Shubhi022,
Currently, the At-home version of the GMAT is available through February, 2021 - although it's likely that it will continue to be available beyond that date (due to ongoing Covid-19 issues around the world).
From your post, it's not clear how long you have been studying (or if you are just beginning your studies). Before I can offer you any additional advice, 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 (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 take the GMAT?
6) 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,
