I did 9 incorrect in verbal ..scaled score is 40
14 incorrect scaled scaled is 28
13 incorrect scaled score is 34
As you see, difference of 6 points in raw verbal is considerable given the fact that you have done only one mistake. this is about 40 point of overall score.

I think verbal raw score depends much much more on how one perfomes in RC and first 15-20 questions. I think the value of CR or SC questions is negligible if compared to the value of those in RC.

I would suggest you to try this scheme: 3 - wrong in first 20 and 7 wrong (without consecutive mistakes) in last 21. with no mistakes in RC!. I am sure the score will be around 36-41.

I am lost on the purpose of this experiment. Since we have no real control over which questions we answer correctly, the only worthy cause I can see is to determine whether earlier questions are more important, and even then, there isn't guarantee that actual GMAT follows the same algorithm.
Yep.

Well, one may use google.com searching for GMATprep questions and answers in order to control the test.
The purpose is to confirm some assumptions and make some more or less certain conclusions.

Hi guys,

This is some of the most extensive work that I have seen. You guys seem to be on the right path to discovery. I would only like to add one more piece of information. To ensure that your results are consistent, please make sure that you do these simulations on this year's GMAT prep; i.e. GMAT prep that was released in April 2010. The GMAT prep released prior to was a lot more adaptive and more agnostic to mistakes early on. Also, ensure that someone is taking this data and summarizing the results for everyone's benefit.

Let me know if you need some help!!

Good luck!!

Guys, check the properties of your GMATprerp.

GMATprer- Old version number 10.0.0.159, volume is 25,5Mb, (no internal build numer).
GMATprer- New version, released in April 2010, number 14.0.0.162, - volume is 24,5Mb, (internal build number is 62562).

@Payal/Rajat

Many Thx... After all I should say, its u people who has suggested this wonderful tip!!

Many thx for that....

I do agree that there is no big deal in knowin the algorithm ..but when u want to pinpoint a theory of How I failed..then these studies comes handy..

After all MBA is all about giving a nice cherry topped theory in a fancy PPT with obscure vocabs called KPI's to lesser known audience!! LOL !!

Still my R&D is going on!!

Payal, Thx for the update!!

Guys, I am requesting soem one to post a snapshot where first 6 is wrong and rest 35 is correct.

I just want to make sure "What is the maximum wrong Iam ALLOWED to do so that I can still score 43+ and in which places I have the legacy to play around??
@pkit

Seems u r in line with my thoughts...plz do post ur results

@uwhusky!!
Dude, I am looking for some serious & constructive stuff...and by no means FUN

I see that you have quite the experiment going on here...there is of course excellent logic behind the idea that doing very poorly early on will leave you with a mountain to climb later. And if you do poorly enough early on then you will be unable to make it up that mountain.

However, this point does not seem to be the valuable one -- who would seek to poorly at the beginning (or in fact at any point in the test)?

The valuable point and the one that seems to keep popping up is this - "Can you do really well on the first 10 or 20 questions and then - because you are running out of time - do poorly on the rest of test and still score well?"

All the evidence that I have ever seen, first hand from my students and otherwise is that you cannot fool the test that way.

Have you tried this? First 20 right (unlikely on test day!) and then just guess "A" for the last 17? What would that score be? That I would love to know.

Also, how do you account for the experimental questions in your studies? Since on the actual test several questions on each section do not count, how does that impact your experiment translating to test day when you do not know if any particular question actually counts?

Interesting stuff guys!

Hello all,

Let me also add something from my side to this R&D.
The attached screenshot is of one of the tests I took some time back.
There are 14 mistakes in Verbal. I mentioned the question types beside the incorrect ones.
I scored 31 in this.
