In CBT, you appear for an
exam that is conducted entirely on the computer. The multiple-choice questions appear on
the computer screen along with the answer choices, and you have to indicate your answer
choice by clicking the mouse at the appropriate place.
Other than the fact that the
mouse does the work of a pen in case of CBT, the two differ on the following counts :
Question/Time Ratio : The CBT
allows more time per question as compared to PBT, having a fewer number of questions than
Scores : In CBT, you get to know
your score immediately on completion of the test. Official score reports, however, are
sent to you later by post, just as in case of PBT.
Skipping questions : Unlike PBT,
the CBT does not allow you to leave a question unanswered. You must attempt a question in
order to get to the next one. And once you have answered a question, you cannot go back to
Adaptive Testing : This is probably
the most important difference between the two kinds of tests. The CBT software is such
that the level of difficulty of your next question depends on the correctness of your
previous response. In other words, no two tests are alike - each examinee will get a
different set of questions to attempt based on his or her ability level. (More on adaptive
testing in the next question)
In a computer-adaptive test,
the computer screen displays one question at a time, which is chosen from a very large
pool of questions categorized by content and difficulty. The test starts out by posing
questions of average difficulty. As you answer those questions, depending on whether you
are correct or incorrect, the test poses future questions accordingly. So if you answer a
question incorrectly, the next question will be easier, with a smaller point value; and
conversely, if you answer the question correctly, the next question will be more
difficult, with a larger point value. The larger number of difficult questions you answer,
the higher score you receive.
Though previous computer
experience is not a prerequisite, familiarity with the use of a personal computer does
help. All CBTs have a detailed tutorial before you actually start the test, which tells
you how to navigate through the test, how to answer, and what the various buttons on the
screen indicate. There is no time limit for this tutorial, so you can make yourself
comfortable before you start answering.
The GMAT requires you to type two
essays for the Analytical Writing Assessment (AWA) Section, within a total of sixty
minutes. This implies that some practice with the keyboard would certainly help. You do
not have to be an expert typist - the AWA is not assessed on the number of words that you
type - but some typing experience will surely stand you in good stead.
For taking the test, you will
be assigned to an individual testing station (similar to a partitioned cubicle in an
office). Other than your admit card and compulsory identification, you cannot carry
anything with you - not even a pen. You are provided pencils, a sharpener, and ample
sheets for rough work.
Yes, you have that option,
but the decision to cancel must be made before you view your scores. Once you choose to
view scores on the computer screen, you cannot cancel them - either at the test centre or
later. Once you cancel the scores, you will not be able to view them.
