The GRE CAT
The Basics of the GRE Computer Adaptive Test
The GRE is computer-adaptive. The computer adaptive test (CAT) is more than just a computerized version of a paper and pencil test. In this format, the computer adapts to your performance as you're taking the test. Understanding how the CAT works and knowing the test-taking strategies appropriate to this particular format will have a direct, positive impact on your score.
How the GRE CAT Works
When you begin a section on the GRE CAT, the computer assumes you have an average score and gives you a question of medium difficulty. As you get questions correct, the computer serves more difficult questions, and increases its estimate of your ability. And as you get questions incorrect, the computer serves easier questions, and decreases its estimate of your ability. Your score is based upon an algorithm that calculates your ability level based not just on what you got right and wrong, but also on the difficulty level of the questions you answered.
You Have One Shot on the GRE CAT
Because each right or wrong answer directly affects the next question, the GRE CAT does not allow you to go back to questions you've already answered and double-check your work. You will see only one question at a time and will not see the next question until you've responded to the one at hand. Once you've noted and confirmed your answer, that's it.
