10 key insights into the GRE:
The GRE selects questions in groups, or stages meaning that
it is critical to perform well section by section rather than question by
question.
The difficulty of questions is governed by performance in
the preceding section. Difficulty levels therefore alter in accordance with the
student's answers as they progress through the later section of the test.
The first section is reflective of an 'average' difficulty
level.
The student has the provision to skip, navigate and return,
and change their responses within a section. However, once they finish with a
section, they cannot return to it.
There is a 'mark and review' feature to mark questions the
student may want to review later.
The student will be scored on the basis of the number of
questions answered, the number of correct answers and the difficulty level of
the sections.
The GRE can be taken once every 21 days, up to five times
within any continuous 12-month period (365 days)
Scores are valid for five years after the test date in which
a student was tested.
There is an on-screen calculator for use in the Quantitative
Reasoning section to reduce the emphasis on computation and to ensure that the
student focuses more attention on reasoning skills.
There is emphasis within the test on the student's knowledge
of vocabulary through reading.
