How to get a perfect 800 score on the GMAT… sort of

 

More than five years ago, I earned a perfect 800 on the GMAT. I don’t really think of it as much of an achievement, to be honest – and I definitely don’t think that it’s an important qualification for the best GMAT tutors.

But I’ve been asked about it literally hundreds of times over the years – by GMAT students, prospective GMAT students, random people in the GMAT forums, strangers who’ve encountered my little GMAT blog, and plenty of others. So here are a few answers to the 800-related questions that keep coming my way.

Did you get every question right? 

No, I’m 99% sure that I didn’t. GMAT enhanced score reports didn’t exist back in 2011, so I can’t actually see if I missed any questions, but as soon as I finished the exam, I worked through every quant question I could remember – and I’m pretty certain that I missed at least one. Maybe more.

The bottom line, for whatever it’s worth: you can miss a bunch of questions and still get a “perfect” GMAT quant score of 51.

But you got every verbal question right? 

I think so. But it was mostly due to dumb luck.

In all of my previous GMAT exams – including the GMATPrep practice tests the first time I took each of them – I always fell short of a perfect verbal score. I inevitably missed a few questions, partly because I tend to lose focus at the end of the GMAT, but mostly because I screw stuff up sometimes, just like every other human.

And if you’ve ever taken the GMAT or the GRE or the LSAT, I’m sure that this part will sound familiar: I inevitably face a few “coin tosses” on verbal – questions where I’m down to two answer choices, but I’m not terribly confident in the final selection. (Incidentally, if you’re down to two choices on a GMAT verbal question and you select the wrong one, that’s not necessarily a sign that you were “close” – it’s usually a sign that you misread something in the passage.)

But when I finally scored an 800 on the GMAT, that didn’t happen at all – I was pretty much 100% confident on every verbal question. That has never happened to me on any GMAT, LSAT, or GRE exam before or since – including the day when I got a perfect GRE score. That test felt freaking brutal, and I was shocked that my GRE score wasn’t lower in the end.

Most importantly, all four of my GMAT reading comprehension passages were bizarrely interesting when I got that 800. I still remember one of them – it was about a type of plant called dodder that apparently has a sense of smell. Amazing. Again, that’s never happened before or since: when have you ever had four interesting GMAT reading comprehension passages on the same exam?

So there you go: yes, I’m pretty good at the GMAT, but those last 10 or 20 points were dumb luck – or measurement error, if you prefer the technical term.

Were you banned from taking the GMAT ever again? 

Yup. I received a nice letter from the GMAT Office of Test Security, informing me that I would need a damned good reason if I ever wanted to take it again. And I don’t have a damned good reason. “I want to help my GMAT students beat your stinking exam” isn’t going to fly with the GMAT test security folks.

My MBA.com account is suspended too, though the GMAT will still happily accept my money whenever I want to buy GMAT practice tests or the GMATPrep Question Pack from them.

Did you study for the GMAT before you got the perfect score?

Well, I earned the perfect score in 2011. I started working as a GRE and GMAT test-prep tutor in 2001, starting with a gig at a large test-prep company before I became an independent tutor a few years later. So in some sense, I “studied” for 10 years before I got a perfect GMAT score – and I’m still “studying,” since I work with GMAT students almost every day.

You probably don’t want to do that. Unless you want to become a GMAT tutor yourself, “studying” for more than a decade is an epic waste of your time.

Are there certain GMAT test-prep materials that would help somebody get a perfect GMAT score?

It’s funny, I read a GMAT blog post from another test-prep company that recommended its own materials for anybody who wants a perfect GMAT score. Frankly, that’s ridiculous, partly because knockoff GMAT materials can never be as good as official GMAT materials – and partly because that particular GMAT test-prep firm writes especially lousy materials, in my opinion.

So, no: other than the official GMAT materials, there aren’t magical GMAT test-prep resources that will get you to a perfect 800 on the GMAT.

And more importantly: there’s absolutely no practical reason for you to want a perfect GMAT score, anyway. An 800 will not help you get into a great business school, and I wouldn’t even argue that it’s a necessary quality for the best GMAT tutors.

So if you’re wondering how to get an 800 on the GMAT, don’t waste your time thinking about that. Go write an interesting MBA essay instead, or better still: go eat a tasty snack.

Inflated GMAT scores… and deflated quant percentiles

 

In the most-commented GMAT blog post I’ve ever written, I argued that the so-called “80th percentile rule” – the idea that top-tier MBA applicants need to score above the 80th percentile on both the GMAT quant and the GMAT verbal section – is mostly a myth.

Why? Well, the unfortunate truth is that GMAT quant scores have increased dramatically in recent years, and you’d now need to earn a 50 (!) on the GMAT quant section to score above the 80th percentile, according to the most recent GMAT data. Here, check this out:

Plenty of things are alarming here. When the GMAT score scale was originally designed, the average quant score was supposed to be 30. Now a quant score of 30 is just the 20th percentile (!!), and the mean GMAT quant score is a 39 – a whopping nine points higher than it “should be” if the GMAT score distribution were actually a bell curve, as originally intended.

Even worse: if you want to score above the 80th percentile, you’ll need a 50 on the quant section. Since a 50 is one heck of a high GMAT score (a 51, of course, is a perfect GMAT quant score), I would still argue that no MBA admissions person in their right minds should actually expect it of you. So if anything, the “80th percentile rule” is more of a myth than ever.

But here’s the part of my original GMAT blog post that may not be true anymore, just a few years later:

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.

Let’s pull this apart a little bit. Would a 710/47Q/40V eliminate all rational doubt about your academic abilities? Yes, definitely. If you can get a GMAT score that high, there’s no good reason to question your ability to handle MBA-level coursework. But is that GMAT score enough to “placate MBA admissions officers”? Probably not anymore, depending on which MBA programs you’re applying to — and, of course, on the rest of your MBA profile.

Here’s the problem: GMAT score averages for top-tier MBA programs have continued to shoot through the roof in the past few years. At Kellogg, for example, average GMAT scores have risen from 712 to 728 in just six years. Stanford’s incoming class of 2018 had an average GMAT score of 737.

I’m sorry, but those GMAT scores are ridiculous. Clearly, the GMAT arms race has gotten absolutely out of control – and I say that as a test-prep tutor who profits from that very same GMAT arms race. It’s as if MBA admissions committees have zero understanding of how standardized tests such as the GMAT actually work: the GMAT’s creators would tell you that the difference between a 710 and a 740 may be nothing more than measurement error.

And that’s before we get into the fact that there’s little evidence that the GMAT is predictive of post-MBA success. But that’s another topic entirely.

To be fair, I can’t blame MBA admissions committees for allowing GMAT score averages to spiral upward. Frankly, it’s much quicker and easier for admissions committees to whittle down a stack of applications based on GMAT scores than it is to ponder the non-quantitative aspects of each MBA applicant’s profile. Plus, MBA programs are forced to play the rankings game – and average GMAT scores are part of those MBA rankings, whether we like it or not.

Unsurprisingly, MBA admissions consultants are advising their clients to chase GMAT scores in the mid-700s – and applicants to elite MBA programs are working harder than ever to raise their GMAT scores. It’s a vicious cycle, and I’d bet that GMAT scores will continue to creep upward.

In any case, if you’re reading this little GMAT blog, you probably can’t do a damned thing about the way things work: you probably just want to get into a good MBA program. So what should you do if an MBA admissions consultant – or worse, an MBA admissions committee member – tells you that you need a GMAT score in the mid-700s?

Well, take solace in the fact that you’re not alone. And if you think it’s unreasonable that you might need a 750 on the GMAT exam, take solace in the fact that you’re probably right.

And then join the rest of the herd. If you have a profile that will allow you to get away with a lower GMAT score, then consider yourself lucky. But if you’re like most people, all you can do is work as hard – and as smart – as you can for as long as you can.

And if you’re already scoring in the low-to-mid 700s but don’t have time to continue studying, maybe it’s worth taking an extra couple of shots at the GMAT, just to see if dumb luck (or measurement error, if you want to be technical about it) might hand you an extra few points next time around. And if you’re a really long way from the GMAT score you want, then maybe it’s time to think about the GRE — but that’s another topic entirely.

Then, please graduate from your top MBA program, become a bigshot in the MBA world, and change the way that the GMAT is handled by MBA admissions committees – because I think that the GMAT arms race encourages even more great business talents to slip through the MBA cracks.

 

how hard is 800?

Before I started to tutor in NYC, one of my old students asked me how long she would have to study to get an 800 on the GMAT.  I told her that she would be crazy to even think about trying.

I meant her no disrespect at all.  She is about to start her MBA program at the University of Chicago, so it’s safe to say that she’s an extremely talented woman.  But achieving an 800 on the GMAT is ridiculously tough.

Let’s start with some stats from the official GMAT site:  fewer than 50 students (out of roughly 250,000) score an 800 each year.  If you’re keeping score at home, this means than an 800 score would fall somewhere above the 99.98th percentile.  And that’s assuming that there are close to 50 people who get a perfect GMAT score–the figure could, in reality, be much smaller.

Now, let’s talk about the torture that GMAT will put you through if you start to get close to a score of 800.  (For the sake of illustration, I’m going to talk mostly about the quantitative section here.  The same ideas apply to verbal, but are trickier to explain.)  On the GMAT math section, formulas are of limited value on difficult questions.  You obviously need to know all of the fundamentals, but it’s easy enough for GMAT writers to cook up an evil question that defies formulaic thinking.

At the highest levels, there are some extremely wicked questions.  Last time I took the GMAT, I ran into an absolutely brutal series notation question that destroyed me.  I spent eight minutes on it, and I still had no idea how to solve the stupid thing.  It was so complex that I couldn’t even remember the question after the test.  And believe me, I was trying like crazy to wrap my head around it, so that I could study it later. Nope.

So basically, the GMAT writers are brilliant enough to lay waste to almost everybody (including arrogant, Stanford-educated GMAT tutors with nearly 10 years of experience), at least some of the time.  I might have gotten 35 questions correct on the quant section last time around (though I’m sure that I made some dumb mistakes somewhere… I can say that I was confident in 35 of my answers, and definitely missed at least two questions), and I scored a 51.  But the GMAT test can still stump me whenever it wants to, apparently.

And let’s talk about that raw quantitative score of 51.  I’ve never heard of anybody getting higher than a 51, and I’ve been stuck on that score for a long time.  Strangely, it’s theoretically possible to get a raw GMAT quant score of 60. (Visit http://www.mba.com/mba/thegmat/gmatscoresandscorereports for an unsatisfying discussion of this topic.)  But I’m pretty sure that I understand what it means to get something higher than a 51:  you need to get those evil questions right, somehow.  I suspect that the impossibly hard GMAT quant questions would have kept coming last year, even if I’d managed to get that series notation beast right.

I’ll go back in to take the test again in the next few months, but the odds that I’ll ever get to 800 remain slim.  There’s absolutely no room for silly errors, and I would have to somehow slug my way through the dirtiest of GMAT questions.  You won’t, of course, find any truly brual, 800-level questions in any official GMAT material, including the GMATPrep and GMAT Focus tests.  So there’s no way to practice, really, once you’re beyond a certain level.

I’m sure that very few of you are really gunning for an 800 (it won’t, in all honesty, really help you get into an MBA program), but I find it fascinating that the writers of the GMAT make it so tough to get a perfect score.
