GMAT Exam/GMAT Focus Edition:
The Quantitative and Verbal Reasoning sections of the GMAT exam and GMAT Focus Edition are computer-adaptive, meaning the difficulty of the test tailors itself in real-time to your ability level. This feature allows the exam to assess your potential with a higher degree of precision and deliver scores that business schools trust.
Here’s how it works: The first question you receive in either the Verbal or Quantitative sections will be of medium difficulty. As you answer each question, the computer scores your answer and uses it as well as your responses to any preceding question to select the next question. If you answer the first question correctly, the computer will usually give you a harder question. If you answer the first question incorrectly, your next question will be easier. This process continues until you complete the section, using responses to all previously answered questions, at which point the computer will have an accurate assessment of your ability in that subject.
You will not be able to skip, return to, or change your answers to questions. This is because the computer uses your response to each question to select the next one.
