Hi Samruddhi2199,
If you selected a School to receive access to your Official Score Report for your 1st attempt, then that School will be granted that access. Thankfully, most Business Schools do NOT care if you take the GMAT more than once, so having more than one Score on your record should not be an issue (and if you score significantly higher on your 2nd attempt, then you can present your 2 results as a positive character trait to the Schools that see both results - re: you don't give up, you rise to face new challenges, etc.).
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 did you score on your 1st attempt (including the Quant and Verbal Scaled Scores)?
2) How long have you studied in total? How many hours do you typically study each week?
3) What study materials have you used so far?
4) 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:
5) What is your overall goal score?
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,
