The GRE CBT Format
Unlike most standardized tests, the GRE is not typically administered in a paper-and-pencil
format. The vast majority of students can take the GRE only on computer, in the
form of a computer-based test, or CBT for short.*
When compared to the paper-and-pencil format, the CBT format has both advantages
and disadvantages. One major advantage is scheduling the test date. In the past,
the GRE was administered only on specific dates throughout the year. Now, due to
computer-based testing, students can schedule the test for whatever time is most
convenient. Another advantage is that a computer-based test uses significantly fewer
questions to determine the score than a paper-and-pencil test, making the total
testing time less on the CBT and giving you more time per question on the CBT than
you would have on the paper-based test.
The main disadvantage of the CBT, however, is that you cannot skip any questions
or return to a previous question to change your answer. Each question must be answered
in the order it is presented, and you cannot view the next question until you have
entered a response for the one already on your screen. The reason for this lies
in how the test is scored: basically, the computer needs to know whether to present
a harder or easier question next, and the only way to determine that is to record
an answer for the current question first.
The other significant drawback to the CBT is that the pacing strategy ideal for
a paper-based test must be abandoned and replaced with a CBT-specific strategy.
On the paper-and-pencil test, questions are presented more or less in order of difficulty:
within each section, the questions start out fairly easy and become progressively
more difficult. Most students breeze through the first several questions and spend
most of their time working on the more difficult questions later in the section.
This seemingly sensible approach would prove disastrous if applied to a computer-based
test, since the first questions in a CBT section are not easy and the subsequent
questions do not necessarily get increasingly difficult. In fact, one test-taker
could easily see twenty extremely difficult questions, while a person sitting five
feet away, taking the same test, might not see even one.
The questions on the CBT also do not all count the same toward a student’s
score; a correct answer on one question may raise the score much more than a correct
answer on another question. By contrast, on a paper-based test all questions are
weighted equally, regardless of difficulty. This is a critical difference, because
it means that some questions on a CBT are more “important” than others
and thus demand more time and attention from the student looking to maximize his
or her score.
TestMasters has developed a systematic pacing strategy specifically for the CBT.
This strategy takes advantage of the way the test is designed, thereby enabling
our students to use their time efficiently. Our students spend more time on the
questions that count the most and less time on the ones that don’t. TestMasters
students learn our CBT-specific pacing strategy in the TestMasters GRE Course and
work through several computer-based practice GRE tests in order to master it.
