Hi nikhilverma22,
Many Business Schools have publicly stated that they do not use an applicant's IR score when evaluating an application, so you likely have nothing to be concerned about in terms of your current IR skills. However, if you're interested in what a specific School/Program thinks about the IR score, then you should research that School directly (you might also consider contacting the School to ask). In addition, if you are looking to improve your IR performance regardless, it's worth noting that IR has a lot in common with Verbal CR (with some RC skills and Quant Tactical skills applicable in certain spots) - meaning that improving your Verbal and Quant skills in specific ways can ALSO help you to improve in IR.
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? What “brands” of CATs/mocks have you used?
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 apply to Business School and what Schools are you planning to apply to?
