Hi inter,
It sounds like you're trying to get a sense of how 'strong' your GMAT scores are. If that's the case, then here's some perspective:
To start, a 660 is a strong score (it's just above the 80th percentile overall), so it could be enough to get you into your first-choice Business School. The percentiles that you're looking at are measures of how well you performed relative to other Test Takers; the Scaled Scores are how you performed relative to the Test. Most Business School expect applicants to score at least a 4.0 on the AWA portion, so you're fine there. Many Business Schools have publicly stated that they do NOT factor in an applicant's IR score when evaluating an application, so your IR5 is fine.
1) What Schools are you planning to apply to?
2) When are you planning to apply?
