Hi aggvipul,
You're ultimately asking an Admissions question, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/Since you're planning to retake the GMAT at some point, is there a particular reason why you want to reactive a prior Score first? If you're planning to purchase the Enhanced Score Report for your first attempt, then the benefit of having that data (so that you can better prepare for your next attempt) makes sense. However, if you're not interested in the ESR, then paying to reinstate a prior Score BEFORE you take your next Official GMAT seems like an odd choice (and an unnecessary expense).
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) What were your Quant and Verbal Scaled Scores on your first Official GMAT?
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 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?
