GMAT is delivered as a computer adaptive test (CAT). In the CAT, the computer screen displays one question at a time, chosen from a very large pool of questions organized by their content and level of difficulty. The first question in a computer adaptive test is always of medium difficulty. The questions that follow are determined by your responses to all the previous questions.
The CAT adjusts to your ability level – you’ll get a few questions, and you may not return to or change your response to any previously answered question, if you guess or answer a question incorrectly by mistake, your answers to the questions that follow will lead you back to the questions that are the appropriate level of difficulty for you. |
