One of my favorite GMAT students recently called me with some great news: he got a 710 on his first attempt at the test (47 quant, 40 verbal). But despite the great composite score, the poor man was disappointed that he only scored in the 73rd percentile on the quant section, since he had heard that MBA admissions committees prefer to see scores above the 80th percentile on both sections of the GMAT. Don’t worry, Mr. 710. You’ll be fine.
I say that for two reasons. The first reason is that MBA admissions committees simply aren’t all that rigid about the so-called “80th percentile rule.” Sure, successful applicants usually have somewhat balanced GMAT scores, but no elite MBA admissions committee blindly applies GMAT score “cutoffs” during its evaluation process. When I look through the my list of former students who were admitted to top ten MBA programs over the past five years, barely one-third of them actually scored above the 80th percentile on both the quant and the verbal sections. The 80th percentile clearly isn’t a magic number anymore—if it ever was.
But there’s a second reason why you shouldn’t worry about hitting the 80th percentile on both sections: GMAT quant scores have changed substantially in recent years. If you had taken the GMAT back in 2007—when the percentile ranking charts in the 11th edition of the GMAT Official Guide were published—a quant score of 47 would have put you in the 81st percentile. Just six years later, a 47 lands you “only” in the 73rd percentile. Similarly, quant scores of 48 and 49 would have put you in the 85th and 89th percentiles in 2007; today, you’d only be in the 78th and 83rd percentiles with those scores.
So if you’re trying to earn a score above the 80th percentile on the GMAT quant section, a 47 would have done the trick back in 2007. You would need a 49 now—and that’s a terrifyingly high quant score for many test-takers.
As I discussed in a pair of old GMAT blog posts (available here and here if you’re curious), the pool of GMAT test-takers includes an ever-growing supply of quant studs, largely from Asian countries. I admiringly call this the “Asian effect”: percentile scores on the quant section are changing quickly, simply as a result of the stronger test-taking pool. Interestingly, percentile rankings on the GMAT verbal section have stayed pretty much constant during the past decade, and that’s probably also a byproduct of the “internationalization” of the MBA applicant pool.
The bottom line? Percentile rankings are disturbingly fluid, and you shouldn’t stress too much about them, especially on the quant section. A 710/47Q/40V is still an outstanding score that eliminates all rational doubt about your academic abilities. For the vast majority of MBA applicants, a GMAT quant score in the 73rd percentile is enough to placate MBA admissions officers, and your odds of admission will depend almost entirely on other elements of your profile.
So if you’re worried about the strength of a 47 on the quant section, don’t be. If you’re north of a 700 with a quant score of 47 or 48, put your GMAT books away. Be proud, be confident, and focus your energy on writing a spectacular MBA application instead. The extra handful of percentile points mean far less to MBA admissions committees than a strong work history and a clear, compelling vision for your post-MBA career.
