In March 1992 the Computer Adaptive Test (CAT) format of GRE was introduced to students. The GRE CAT superiority lies in its ability to asses the students level of intellect and present questions accordingly.
The question paper pattern of the paper based test has been retained. The only differences between the paper based GRE and GRE CAT are In GRE CAT the questions are answered on a computer instead of paper and the questioner differs from person to person depending on their intellect.
The advantage in the CAT format of GRE is that, instead of all the students answering to the same set of questions, the GRE CAT test adapts itself according to the performance leave of the student. This is achieved through a set of practical rules that the GRE CAT follows.
Question Presentation in GRE CAT
The Student is put forth with the easiest of the questions at the beginning of the test. Based on the answer that is chosen, i.e. whether it is the correct or the wrong answer the next question gets chosen.
If the student selects the wrong answer, the next question presented would be of the same level as the first question. This same pattern is followed through out the GRE CAT test.
If the student answers the question correctly the difficulty level of the next question would increase. With the difficulty of the questions the score level too increases. Hence, the number of difficult questions the student answers the more score he gains.
First 10 Questions
Since the first few questions play a crucial role in the progress of the test level, the students have to be more careful at the beginning of the GRE CAT test.
Remember answering the first 10 questions correctly in GRE CAT will take you closer to a GRE score of 800 even if you answer the remaining questions wrongly
First 10 wrong and subsequent questions correct will not fetch you much of a score.
Keep this in mind and spend more time and effort in answering the first 10 questions of GRE sections correctly
