The GRE® Test is a CAT (Computer Adaptive Test). This means that the computer adapts the level of the questions to the test-taker’s ability. Initially questions of medium difficulty level are administered to test – taker. If he / she answers these questions correctly, a more difficult question is given. Otherwise, an easier question is administered. So, at every stage, the computer tailors the test to the examine’s level. In this examination, the score depends both on the number of questions attempted and the number of correct responses.
Some points which you must know about the Computer Adaptive Test :
In verbal section each question has five answer choices and you must select one choice as your answer. In the quantitative ability section each problem solving and data interpretation question has five answer choices. However, quantitative comparison questions have only 4 answer choices. Only one question appears at a time. To move to the next question, you have to mark an answer to the question that is currently on your screen. Once you have confirmed your answer to a question you can’t go back to a question and change your answer. The questions are graded into 5 categories ranging from the easy to the hard category. More points are awarded for getting the harder questions right. You are penalized for not completing the test. Hence, your score depends on your accuracy, the difficulty level of the questions and the number of questions you attempted. At the beginning of the test, every candidate gets a question of average difficulty level (level 2 or 3). Questions in the verbal and the quantitative sections need not always be administered in groups. For example, if the first question that appears in the verbal section is an antonym, then you need not necessarily get a series of questions on antonyms alone. Two questions on antonyms may be followed by one question on analogies, followed by one on sentence completion. In other words, questions can appear in any particular order. Similarly, in the quantitative section, one question on problem solving may be followed by one question on quantitative comparison. This may be followed by one question on problem solving. Hence, the type of question that will come next cannot be predicted
