*** Wonderful features added to the ESR Analytics ***

GMAC has done a brilliant job on the ESR this time. Our feedback has been considered and product has been enhanced.


!
Please Upload your enhanced score report here if you have the new one! Thank you.



Those who have given the GMAT and have paid for the ESR report earlier got the ESR report which was not worth spending $27. this time GMAC has come up with BETA version of ESR Report and this is far informative than that we received earlier. Now, You will get the following in the ESR report with graphs and pie chart as well as summary text:

1. Overall score
2. Scaled score section wise - PS,DS,SC,CR,RC
3. Scaled score question wise - Arithmatic, Algebra & Geometry
4. Percentage of questions you marked correctly, Average difficulty, time taken for first 9, second 9, third 9 and final 10 questions in quant AND first 10, second 10, third 10 and final 11 questions in Verbal.

if you have ever paid for ESR report then:
1. Go to MBA.COM
2. Login to your account
3. click on ESR REPORT
4. you will get a link on your email
5. This link will give you new version of ESR report. (doe not matter if you have ever downloaded the report earlier)

I am sure this will help you figure out what did you messed up or did well on in your GMAT attempt. Enjoy the new analytics :)

P.S. - If we can get such data from multiple users then we will be able to do the algorithm analysis very well. Till now we only had GMATPrep data. we have been really unsure of GMAC algorithm. but some data analytics on the data provided by gclub users can open multiple aspects of the algorithm.

For the quant section i have added the images capturing the updated parts of the report. isn't that brilliant :)

It's nice that the GMAC has slowly added features to the ESR over time. It would be especially helpful if the GMAC were to provide per-question timing information and correct/incorrect for every question, as well as indicate exactly which questions were experimental, but hey, beggars can't be choosers I guess. At the moment, it's moving in the right direction for sure, but it's still just vague enough to keep the precise GMAT scoring algorithm inscrutable.

On page 2 of this thread, Dabral has already concluded from the updated ESRs that 9 of the 37 quant questions are experimental, and that 11 of the 41 verbal questions are experimental, which was the common wisdom up to this point, but it's nice to have it confirmed.

"What about the IR section," you ask?

The information we need lies within an especially revealing new feature: the "Percent of Questions You Answered Correctly" in the "Integrated Reasoning Performance" section.

One take-away from the newly updated ESR's I've seen so far is that the IR section always has 9 questions that count, and 3 unscored/pretest/experimental questions. According to the GMAC, somewhere from 8-12 of the IR questions count. However, GMAC has indicated in the past that "all students have the same amount of experimental questions," which would further support the hypothesis that there are exactly 9 out of 12 questions that will count toward your score (the ESR does not provide information on whether you answered the experimental questions correctly), and 3 experimentals.

In most cases (but not all--see examples below!), your IR score is simply the number of questions that you answered correctly out of the 9 questions that counted. However, as you can see, IR scores are also prone to being scaled upward by a point, especially on the high end of scores, and depending on the difficulty of the section.

Despite the GMAC's vague official answer that 0-4 IR questions (out of 12) are experimental, every ESR with this expanded information that I've seen so far has supported the hypothesis that it's always 9 questions that count.

How do I know this? Because the percentages of correctly answered questions that I've seen so far have always aligned with a denominator of 9 (percentiles rounded to the nearest integer):

1/9 = 11%
2/9 = 22%
3/9 = 33%
4/9 = 44%
5/9 = 56%
6/9 = 67%
7/9 = 78%
8/9 = 89%
9/9 = 100% (but you would still get an "8" because the IR section is scored out of 8 points).

This exact same denominator method can of course be used to determine the number of experimental questions on Quant (9 of 37) and Verbal (11 of 41). UPDATE 4/5/18: On the updated, shorter GMAT, the number of experimentals has lowered from 9 to 3 on Quant, and 11 to 6 on Verbal, beginning 4/16/18. However, the number of experimentals on the IR section (3) has stayed exactly the same.

Below are some examples, taken (with permission) from some of my private students and from GMAT club screenshots. Being able to precisely infer the number of experimentals on each section should provide helpful implications for GMAT strategy. The GMAC may have unintentionally disclosed some information that it would have preferred to keep confidential, which is exciting to me! Of course, this could always be modified in the future, but it's still good to know for now.

Image

Notice how this student scored a 1 out of 8 with 1 of 9 questions right (11.1%).

Image

Notice how this student scored a 2 out of 8 with 2 of 9 questions right (22.2%).

Image

Notice how this this student scored a 3 out of 8 with 3 of 9 questions right (33.3%).

Image

Notice how this student scored a 4 out of 8 with 4 of 9 questions right (44.4%).

Image

Notice how this student scored a 5 out of 8 with 5 of 9 questions right (55.5%).

Image

Notice how this student scored a 5 out of 8 with only 4 of 9 questions right (44.4%). The IR scores on this GMAT must have been scaled upward to reflect the overall difficulty of this particular IR section.

Image

Notice how this student scored a 6 out of 8 with only 5 of 9 questions right (55.5%).

Image

Notice how this student scored a 7 out of 8 with 7 of 9 questions right (77.7%)

Image

Notice how another student scored a perfect 8/8 with 7 out of 9 questions right (77.7%).

Image

Notice how this student scored a perfect 8/8 with 8 out of 9 questions right (88.8%)

Image

Of course, 9 out of 9 (100%) will earn you a perfect 8/8 as well!

One thing that can be gleaned from the ESR data is that the quant section does indeed have 9 experimental questions and the verbal has 11 experimental questions. These numbers were what I had seen mentioned for the longest time, but this is the first time it is being confirmed by official data.

And further we can figure out the distribution of the experimental questions. In quantitative, the distribution is 2, 2, 2 and 3, in the chunks of 9, 9, 9, and 10 questions respectively. In verbal, the distribution is 2, 3, 3, 3 in chunks of 10, 10, 10, and 11 questions. One can conclude this from the percentage correct data for the individual scores that have been reported here by students so far.

I've noticed that the GMAT enhanced score report has been enhanced, which I guess makes it a double-enhanced score report. :-D

There are 2 additional pages, one for each of the main sections: Verbal and Quant.

The additional sections of the enhanced score report show 3 pieces of information

1. The percentage of questions answered correct/incorrect for each quarter of the section.

2. The average difficulty of each quarter of the section.

3. The average time spent per response for each quarter of the section, broken down by incorrect/correct response.

And the great news is, if you have ordered an enhanced score report in the past when the report did not contain this new information, you can request access to your enhanced score report again, and your new enhanced score report will show the 2 additional pages. I have just requested my "double-enhanced" score report and find it super helpful.

Looks like the new enhanced score report is still in beta testing, so I'm not sure if it is available to everybody. But I think it's worth a try.

Hope this helps.

I just took my gmat this week. I didn't realize this was a "new" report - I found this report to be helpful, but I wish there was a bit more of a quant break-down. My numbers are similar to mvictor and HKD1710 - I just didn't finish strong and therefore I scored a 47.

File comment: It would have been nice to see more of a break-down of the quant than just "Arithmetic" and "Algebra/Geometry", but then again, the more you break it down the harder it is to infer meaningful info from a small sample, so I'm not sure it would have really helped much.

Why do you think there are 9 and 11 experimental Qs in quant and verbal?


Because 2,2,2,3 are the numbers needed for the percentages to make sense for the Quant divisions.
2+2+2+3=9
2,3,3,3 are the numbers for Verbal.
2+3+3+3=11

Does this make sense?

Hi Nina1987,

If you look at the attached score report you see that the student got 29% incorrect in the second set of 9 questions. The 29% can only result if the student missed 2 questions out of 7, which is 28.57% and is rounded up to 29. This means that only 7 questions out of 9 are counted towards one's score, and 2 are experimental. I did the same analysis on the rest of the reports posted on this thread and one ends up with the distribution of experimental question during the test that I listed earlier.

Cheers,
Dabral

Im afraid I still dont get. :(

Continuing your ex. the person would have spent 1min 20sec on an average. Now if the pie chart shows 50-50% red and blue, do you mean she/he spent 40 secs on avg on correct and incorrect questions?


You do not have to assume this. when you move the cursor over the red and blue part you see the individual average time. this will happen only when you open the ESR with the provided link. the same will not happen after to save the report as a pdf.

Hello, I would just like to add my ESR. I scored a 780 overall with a 51Q and 48V. I had not originally planned on ordering it considering my score, but felt it may be useful data for those who are wanting to know what it takes to receive a high score. Plus, I was quite curious!

Only 1 question wrong in verbal and V48 for only 1 wrong and that too the difficulty is off the charts(literally ), I thought at least 790 would be the result of this.

what do you guys think?

Yes, that's correct--we have learned from his ESR that only 1 wrong on Verbal can drop you down to 48/51. I think that the only way to score a 790 is to get a 51/51 (100% correct) on Verbal, because a perfect 51 on Verbal is much less common than is a perfect 51 on Quant. Also, let's congratulate lin11 on being only 1 question away from a perfect 800! Amazing job.

strange thing though with verbal
V38
first part 62%
second part 57%
third part 71%
fourth part 62%

mine 30:
1st - 62%
2nd - 71%
3rd - 86%
4th - 62%

although I was better of overall, I got a lower score.
I really don't understand why getting to the hard verbal questions is so hard, even though you answer questions correctly...
