Hi Aadi01,
I'm sorry to hear that your first attempt at the GMAT did not turn out better. Thankfully, Business Schools don't care if you take the GMAT more than once - and now that you've faced the Official GMAT, you know the specific details of what Test Day involves, so you can better prepare to face all of them for this next attempt.
Before I can offer you the specific advice that you’re looking for, it would help if you could provide a bit more information on your prior studies and your goals:
Studies:
1) How long has it been since you were in a consistent study routine? In the lead-up to your 1st GMAT, how many hours were you typically studying each week?
2) What study materials do you currently have access to? Which "brands" of CATs/mocks have you taken already?
3) Was your Official GMAT (back in January, 2020), the last time you took a full-length Exam? Have you taken any practice CATs/mocks since then?
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,
