Hey Karan,
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).
If test-takers all get a similar percentage correct, how does the GMAT distinguish among different performance
levels? “Regular” school tests gave everyone the same questions and performance was determined based upon percentage correct. 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.
Hope this helps!
Best,
