Watch the video “GMAT Tip: How the GMAT is Scored” (above) for a comprehensive overview of how the GMAT exam is scored. In the video, Brian Galvin, Director of Academic Programmes at Veritas Prep, suggests approaches to the test which will help you improve your performance and achieve a competitive GMAT score. He illustrates how you should “adapt to an adaptive test”.
Additionally, find here even more details on how it works. The GMAT test software adapts the test to your ability level. If you can answer hard questions correctly, the test gives you even harder ones. In this way, it assesses just how good you are. Vice versa, if you answer questions incorrectly, the test gives you questions on the same level or easier ones to check where your bottom line is. Naturally, the harder questions bring you a higher GMAT score, and easy questions keep your score low.
Your GMAT score (200-800) is based on 37 math questions and 41 verbal questions. Actually, the number of real questions is even lower, because there are always experimental questions. These are potential questions that GMAT is evaluating and they do not count against your GMAT score. However, there is no way that you can recognize the real ones.
You will know your GMAT score (200 - 800) immediately after the test, but just for the Verbal and Math sections. But this is exactly the score which business schools mention in their admission requirements. The scores on the Analytical Writing Assessment and the Integrated Reasoning sections will be reported later and these are also taken into consideration when AdComs evaluate your application.
