I am a professional GMAT tutor who is still on his own quest for a perfect 800 on the GMAT, and this issue has been nagging at me for some time.

According to the GMAC, test scores on both Quant and Verbal range from 0-60. However, the evidence has reliably shown that the best possible Quant and Verbal scores are actually 51, not 60.

My theory: students who actually should have scored 60/60--all 28 (Quant) or all 30 (Verbal) questions that counted correct--are given 51s. Why? Because given the adaptive nature of the GMAT, where a correct answer usually yields a harder question until the difficulty level is literally off the charts, this is so unlikely that the GMAC just went ahead and clumped all the top Quant/Verbal scorers into the Q51 category, whether they got all the questions that counted right, or around 95% of those questions right.

Still, it is frustrating that the GMAC seems to be clinging to its claim that you can score higher than 51, when all available evidence points to the contrary.

Do you have any student that has actually answered all counted questions correctly on a real test?

Not that I know of (not all of my students have had the benefit of / taken advantage of the Enhanced Score Report, which provides some of this information). It would be helpful to see an ESR from someone who got every question right, but I haven't seen one of those yet (maybe because it's virtually impossible!).

That being said, there have been been thousands of debriefs on GMAT club, and not one of the section scores I've seen has been higher than 51 on either Verbal or Quant, other than the occasional fake one where someone got a little crazy with the Photoshop.

If someone out there has evidence to the contrary, then please feel free to disprove me. It's just a working theory of mine at the moment.

Hi mcelroytutoring and HanoiGMATtutor

Hi guys, I know this thread is old, but I thought I'd throw a data point your way: I got a 51V in 2016. I later ordered my ESR and found out that I'd gotten 100% of the questions correct. So as far as I can tell, 51V must be the absolute maximum.

I was surprised to see that the difficulty level of my questions was rated as medium up until the final fourth of the exam, when it went to medium-high. How weird!

I excerpted the two pages of the ESR that deal with verbal and have uploaded them in case there's anything else there useful for you guys.

FYI, I'm a tutor, too. I've been coaching GMAT verbal since 2013, and added quant when I moved from Paris to Berlin in 2015. I've been working for other people all this time, but will soon be heading out on my own, so I'll likely become a more frequent visitor to these here parts.

Thanks for the contribution, jennpt !

Yes, ESR research so far has confirmed that you need to answer all 30 counted questions correctly on Verbal to earn a perfect V51. In fact, just 1 wrong will drop you down to a V48.

As for Quant, you can get 0, 1, or even 2 wrong in some cases and still earn a Q51. On the other hand, I have also seen an example of a Q50 with only 1 counted question wrong.

Finally, it is also possible to score Q51, V51, 790, thus missing a perfect composite score of 800 by the narrowest of margins. This occurs when you receive a perfect score on Quant and Verbal, but answer at least one question incorrectly on Quant.

In other words, you have to answer all 58 (counted) Quant and Verbal questions correctly to earn a perfect 800.

Hi,

It's really interesting that why GMAC doesn't disclose its grading method clearly. Why it should be a secret?:) I have another question though, what do you mean by counted question?Are there uncounted questions too?

Hi Mehemmed,

Yes, there are uncounted questions--quite a lot of them, in fact (23 of 90 total).

GMAC calls them "pretest" questions, but I like to refer to them as experimental questions. They (supposedly) do not count at all toward your score and are used for research purposes only.

On the real GMAT, there are 11 experimentals on Verbal, 9 on Quant, and 3 IR, for 25.6% of the test.

Thanks for the info. I knew that there are experimental questions on GRE, but I wasn't aware of that is the case on GMAT as well.
