In the previous post you said that The score algorithm doesn't care about the number of question answered correctly. It cares about the difficulty of each question.

As I understand GMAC scoring algorithm (Please correct me if I am wrong) - as you answer the questions correctly the difficulty level goes up. Suppose, in the first 10 questions, I answer the first 5 questions incorrectly. Will I get 6th question as 700 Level question?? I guess NO. And Suppose, by any chance if get 6th question as 700-Level question and I answer it correctly, Will the system evaluate only 6th question for scoring??


[Suppose, in the first 10 questions, I answer the first 5 questions incorrectly. Will I get 6th question as 700 Level question??]
Of course No. Your guess is correct. Why? Because the system determines that your real ability is low (ie 500-600), so why should it get you a 700 question?

[And Suppose, by any chance if get 6th question as 700-Level question and I answer it correctly, Will the system evaluate only 6th question for scoring??]
No. LOL, why on earth do you think that the system counts only on those questions you answered correctly? It counts all questions and generate the overall score.

The simple answer here is that even when you answer 100% of questions correctly, the question difficulty level does not continue relentlessly upward in a straight line. The test also has other concerns, like feeding you questions of every type/sub-category, and serving you about 15% experimental questions, whose difficulty levels are set in advance.

Also, GMAC is notorious for understating the difficulty level of the questions on the Verbal section. As you noted, even perfect V51 scorers don't see the overall difficulty level go very high, but we know this not to be the case--there are in fact some very difficult questions mixed in there, but the blue line in the ESR only reflects the average difficulty of all questions in that quarter.

Great Initiative!! These analyses and results are really very helpful to devise a foolproof strategy.
I was thinking to follow a specific strategy in verbal, so I wanted to check with everyone here.
Generally, I am a little slow in verbal, it takes 2-2.5 mins for me to dissect SC and almost the same time in CR, which eventually reduces the time for RC. So I was planning to take an approach in which i will answer all questions properly except I will guess 1 RC completely(probably the third one). Is it possible to test this scenario? I am curious to see the results because this will give me much more time to focus all other questions.
Thanks in advance

Thanks a lot for the experiment!

I have one question concerning the GMAT.
For instance, if we don't know a question and we want to skip it. Would we get penalized more by instantly picking answer or by waiting a period of time and then pick an answer?

Thank you!!!

Hi gmatgood,

The amount of time that you spend on a question is NOT a factor in your Score. By extension, if a question is too difficult, then 'dumping' it sooner (rather than later) would be beneficial - since you would then be able to spend that time on other questions.

1) How long have you been studying for the GMAT?
2) What is your goal score?
3) When are you planning to take the GMAT?
