For each multiple-choice section of the GMAT exam, there is a large pool of potential questions ranging from a low to high level of difficulty. Each section of the test starts with a question of moderate difficulty. 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 will continue until you complete the section, at which point the computer will have an accurate assessment of your ability level in that subject area.
