Can someone please share his/her experience on this...
I am targeting a score range of 650-680,How many questions should I be aiming to get it correct both on Quants and Verbal?
An early response will be highly appreciated.
Cheers
Karan
Dear Karan,
I'm happy to respond.
What you are asking betrays a very common misunderstanding about how the GMAT is scored. Folks not familiar with the test sometime imagine that this-many right answers translates to a particular score. That is 100% not true. Two different students could get roughly the same number of questions correct, and one get a 450 and the other get a 750.
You see, the GMAT Q & V sections employ
Computer Adaptive Testing. For a detailed explanation, see:
https://magoosh.com/gmat/2012/what-is-th ... tive-test/You see, as you get questions correct, on the Q or V section, the computer starts to feed you harder and harder questions. As you get questions wrong, the computer starts to feed you easier and easier question. If P got a 450, that probably means he got many of the medium difficulty questions incorrect, and didn't start getting any correct until the questions got very easy. If Q got a 750, that probably means she got all of the medium questions correct and didn't start getting any questions wrong until they got very hard. The score you get doesn't not merely depend on number of questions you get correct. What matters is the precise difficulty rating of each particular question, and whether you got it correct or not correct. In this example, P & Q probably would not see more than a couple questions in common, and yet, through the magic of psychometrics, both scores are fair. In fact, thousands of people take the GMAT, but in all likelihood no two have the exact same sequence of questions, yet again, through the magic of psychometrics, all the scores are fair. The algorithm that the computer uses is very complex --- it is proprietary knowledge of GMAC, so none of us know exactly what it is, and probably even if we knew it, it would be too difficult to understand with a Ph.D. in statistics of something of that nature.
If you want a competitive score, you need to get correct the questions that most test-takers get wrong and you need to make as few mistakes as possible with the easy & medium questions.
Does all this make sense?
