What is a Computer-Adaptive Test?

In a Computer-Adaptive Test (CAT), questions are selected while each individual takes the test. At the start of each multiple-choice section of the GMAT, you are presented a question of middle difficulty. As you answer each question, the computer scores that question and uses that information––as well as your responses to any preceding questions and information about the test design––to determine which question to present next. As long as you respond correctly to each question, questions of increased difficulty typically will be presented. When you enter incorrect responses, the computer typically will present you with questions of lesser difficulty. Your next question will be the one that best reflects both your previous performance and the requirements of the test design. This means that different test takers will be given different questions. The selection of questions you will see is based on your responses to all previous questions, and because the CAT adjusts to your individual ability level, you will get few questions that are either too easy or too difficult for you. Because the computer scores each question before selecting the next one, you must answer each question when it is presented. For this reason, once you answer a question and move on to another, you cannot go back and change your answer. The computer has already incorporated both your answer and the requirements of the test design into its selection of your next question. Each computer-based test section meets pre-established specifications, including the types of questions asked and the subject matter presented. The statistical characteristics of the questions answered correctly and incorrectly, including their difficulty levels, are taken into account in the calculation of scores. Therefore, scores of all test takers can be compared even though they received different questions.

What computer skills do I need?

Minimal computer skills are required to complete the GMAT™. It cover things such as using a mouse, entering responses, moving on to the next question, using the word processor, and accessing the Help function. Although you will be able to access the Help function at any time during the test, you should note that any time spent reviewing the Help screens will count against the allotted time for the test section you are working on.
