What is V 31... How it is calculated?.... If i want to Reach V 40+ what should i do? How many questions need to be answered correctly to reach V40 from V 31 ?

Hey,

Good question! Below you'll find some information from our free PDF guide, The GMAT Uncovered. You can download this PDF here: http://www.manhattangmat.com/gmat-uncovered.cfm

Also, if you have any more questions about scoring, you might consider attending one of our free informational GMAT Preview sessions. You can find upcoming Live Online GMAT Preview sessions here: http://www.manhattangmat.com/free-gmat-prep-course.cfm

Scores on the GMAT are not based on the percentage of questions answered correctly. Tests you took in school were generally based on percentage of questions correct: the more you got right, the higher the score you received. As a result, we have been trained to take our time and try to get everything right when we take a test. This general strategy does not work well on computer-adaptive tests such as the GMAT. On the GMAT, most people actually answer similar percentages of questions correctly, typically in the 50% to 70% range (even at high scoring levels).

On the GMAT, everybody answers different questions, some easier, some harder. You can think of the GMAT as a test that searches for each person’s “60% level,” or the difficulty range in which the person is able to answer approximately 60% of the questions correctly. (This is not exactly what happens, but it’s a good way to think of the difference between “regular” tests and computer-adaptive tests.) Your score will be determined by the difficulty of the questions that you answer correctly versus the difficulty of those that you answer incorrectly.

An individual, two-digit score, called a scaled score, will be calculated for the Quantitative and Verbal multiple-choice sections. While both sections will be scored on a scale of zero (low) to sixty (high), the two scoring scales are not the same. For example, a scaled score of 40 on the Quantitative section represents the 58th percentile, while a scaled score of 40 on the Verbal section represents the 89th percentile (all statistics as of November 2009). Essentially, the same scaled score, 40, represents a much higher performance on Verbal than on Quantitative.

The two individual sub-scores are then converted into one three-digit scaled score given on a scale of 200 (low) to 800 (high). The exact conversion mechanism, from two-digit sub-scores to three-digit scaled score, has not been made public by the testmakers, but the Verbal sub-score appears to be given somewhat more weight in the overall score than the Quantitative sub-score (this effect can range from minimal to mild, depending upon the exact mix of sub-scores).
