I scored a 710 (49-Q, 39-V) on my second GMAT. I just got the score report back and scored a 5/6 (which is good enough) on the AWA and a 5/8 on the IR. I know the IR is a little on the low end. My first GMAT I scored a 640 (I didn't study as much or put the time that I needed to score a 700+), but my IR was a 7/8 (AWA 5/6...so no different). I plan to apply to some top 20 mba programs in another 3 or 4 years or so. I'm happy with a 710, and especially since both my verbal and quant sub-scores are greater than 80th-percentile. I work in consulting and do a ton of statistical/data analysis, so I do not believe a 5/8 on my IR really reflects my ability in those areas. Also, a 5/8 isn't necessarily "bombing" that section, it just isn't an elite score that correlates with the rest of my profile.
So my question is: is a 5/8 on my higher overall score GMAT a pause for concern? Considering that I received a 7/8 on my first GMAT (though the overall score was lower), my quant score was still strong, the IR is a relatively new section, and I work with data every single day. I'm open to any thoughts, feedback, and suggestions. I will say: I would highly prefer not to take the GMAT again....I'm super busy with work and the philanthropic organizations I volunteer with on my weekends. Thanks in advance for the help.
