Hi IRBlues,
It's likely that these two scores would be viewed by Admissions Committees in the exact same way - a 730/Q48 and a 710/Q47 are both outstanding scores (at or above the 90th percentile overall), so you can apply to any Business Schools that interest you (and with either Score). Many Business Schools have publicly stated that they do NOT consider an applicant's IR score when reviewing the application, so it's likely that you have nothing to worry about there. As long as your AWA is a 4.0 or higher, then you're 'set' with either score.
When are you planning to apply to Business School?
What Schools are you planning to apply to?
